Aqua-Mite is a specially formulated two component coating system which can be applied to almost any type of surface for the purpose of water proofing same.

Aqua-Mite operates once dry optimally at ambient temperatures. Variations from this temperature diminish the effectiveness of the product proportionally.

Aqua-Mite consists of a unique blend of hi-tech powders in pack one and in pack two, a very special fluid chemical blend , which, when added to the powders in pack one forms an extremely potent surface coating which can withstand constant water presence.

Aqua-Mite can be used to repair specific leaks in a substrate or for general water proofing.

Aqua-Mite is perfectly safe for use with potable water.

Aqua-Mite is a quick dry waterproofing.

Aqua-Mite is resistant to a wide variety of acids.

Aqua-Mite can be used for the following applications:

  • Reservoirs (concrete, brick, block, cement plaster, steel etc.)
  • Koi ponds
  • Fish pondsPools
  • Water features
  • Waterscapes
  • Tanks (Asbestos,steel, polypropylene, Polyethylene, Glass fiber etc.)
  • Dams

Aqua-Mite is activated with a specially formulated compound which will inhibit the growth of algae on it`s surface. This technology represents a first for underwater coatings.

Cosmo-Dec`s hi tech approach to it`s coating technology means we are always at the forefront when it comes to new innovative ideas.

Our coatings contain active ingredients that literally clean the water.

 

Surface preparation

The substrate onto which Aqua-Mite is to be applied must be clean of loose dirt, dust, grease, grime, old flaky paint etc. The substrate must also be dry.

In the event of cracks or splits or holes in the substrate, these can be mended with a thicker mixture of Aqua-Mite worked into the crack or hole with a spatula and once dry (About 2 hours) can be over coated with Aqua-Mite as a paint. A membrane can also be used in conjunction with Aqua-Mite for obstinate repairs as well as the addition of plaster sand with the crack fill mixture for larger cracks or repairs.

Mixture

Mix one part of Aqua-Mite fluid with two parts of Aqua-Mite powder by volume in a suitable container. Stir for a couple of minutes or until all the powder is mixed with the liquid and there are no lumps. Mix only enough to last for about a half an hour as the mixed Aqua-Mite has a pot life of about one hour depending on weather conditions. Brushes and equipment can be washed with ordinary tap water, warm and soapy preferably, as the product is miscible in water.

Application

Apply the mixed Aqua-Mite by brush, roller or spray applicator onto the suitably prepared surface. We recommend two coats 24 hours apart and the brush strokes should be at right angles to one another per application.

In the case of reservoirs or where water is stored, water can be contacted the Aqua-Mite coating after 24 hours, although the Aqua-Mite will dry within 30 to 60 minutes.

Coverage.

Aqua-Mite covers approx. 3 square meters per kg.

Colours

Aqua-Mite comes in a variety of colours viz.

Blue, Green, Red, Grey, Black, Yellow Coloured Aqua-Mite costs  R200-00 per pack more than standard grey.

All the above colours come in light and dark shades. The dark shades cost 20% less than the light shades. (Prices quoted on our price list are for dark colours)

Aqua-Mite is expected to last for a life time under water, baring mechanical damage.

Aqua-Mite is truly a remarkable new age product, very cost effective, easy to use and can turn a novices work into a professional work of art.

This amazing product has been the system of choice for contractors and other professionals for almost 2 decades.

Now for the first time Aqua-Mite is available for use by the home owner for all those niggley repairs that would normally cost an

arm and a leg to have done by a plumber or a contractor.

Do, for a fraction (A few Rand) of what they charge (Up to R5000-00 or more) yourself, by using the products that they use.

The secret is out!

 

Concrete substrates. (Reservoirs, floors, roofs, showers, pools, ponds {Fish, Koi etc.}

Treating a hairline crack

Clean the substrate with a firm brush provided down to it’s original condition. Wipe away all loose dust and ensure the surface is

dry.( If hairline cracks are visible don’t do anything special to them.)

Mix sufficient of the powder and the liquid together in the 5 Lt. rectangular container provided to do the area you are about to treat.

Add the powder to the liquid whilst stirring ensuring there are no lumps.

The mixing ratio for this coating is 2 Powders to one liquid by volume. The entire packet of powder and whole bottle of liquid can

Cover, in this way, about 5 square meters applying 2 coats. Use pro-rata measurements for smaller areas.

First work into the crack with the paint brush provided the mixture. Allow to dry (About 30 minutes on a sunny day)

Then paint one coat of the mixture over the length of the crack about 50 mm wide.

Wait for about 30 minutes for that coat to dry.

Apply a second coat over the first coat.

Please remember that once mixed, the mixture has a limited pot life. So mix only enough to treat the specific task you are

Undertaking.

 

Treating a larger crack.

With a chisels edge, screw driver or other sharp metal edge, open the crack in a “V” shape about 10 mm wide and 10 mm deep.

Brush away loose dirt. Make sure the surface is clean and dry.

Mix 1 part of powder with one part of the silica provided and about one quarter part of the white liquid plastic to make a paste.

Work, with the spatula provided, this paste into the opened crack. Smooth over with the spatula. Allow to dry (About 30 minutes)

With the sand paper provided sand down the dried paset to provide a smooth surface flush with the surrounds.

Apply 2 coats of Aqua-Mite paint mixture (2 powders to one liquid by volume) over the treated crack one at a time allowing drying

time in between.

 

Treating a large crack where the substrate is weak.

Proceed as with the larger crack above up the point where you have smoothed over the dried paste with sand paper.

Cut a piece of membrane from the roll provided about 100 mm longer than the crack.

Mix some Aqua-Mite paint mixture (2 powders to one liquid by volume) and paint a thick coating as wide and as long as the

membrane you’ve just cut over the repaired crack. Whilst the Aqua-Mite paint is wet, stick the membrane over the repaired crack

into place using the Aqua-Mite as an adhesive. Iron out all the folds and bubbles in the membrane. Paint 2 coats of Aqua-Mite

paint mixture over the entire membrane that has been stuck in place, allowing for drying time between coats.

 

Plastic tanks (Cracked)

At each end of the crack make or drill a small hole about 3 mm in dia.to prevent the crack from running.

Then with the sand paper provided roughen up (Key) the area to be treated. About a 100 mm longer than the crack and as wide

as the membrane. Brush away loose dirt. Make sure the surface is clean and dry. Mix sufficient of the powder and the liquid together

in the 5 Lt. rectangular container provided to do the area you are about to treat.

Add the powder to the liquid whilst stirring ensuring there are no lumps.

The mixing ratio for this coating is 2 Powders to one liquid by volume. The entire packet of powder and whole bottle of liquid can

Cover, in this way, about 5 square meters applying 2 coats. Use pro-rata measurements for smaller areas.

First work into the crack, with the paint brush provided, the mixture. Allow to dry (About 30 minutes on a sunny day)

Then paint one coat of the mixture over the length of the crack about 50 mm wide.

Wait for about 30 minutes for that coat to dry.Apply a second coat over the first coat.Please remember that once mixed, the mixture

has a limited pot life. So mix only enough to treat the specific task you are Undertaking.

Mix some Aqua-Mite paint mixture (2 powders to one liquid by volume) and paint a thick coating as wide and as long as the

membrane you’ve just cut over the primed crack. Whilst the Aqua-Mite paint is wet, stick the membrane over the crack

into place using the Aqua-Mite as an adhesive. Iron out all the folds and bubbles in the membrane. Paint 2 coats of Aqua-Mite

paint mixture over the entire membrane that has been stuck in place, allowing for drying time between coats.

If possible repair the crack on the INSIDE of the tank.

 

Joints, seems, cracks, overlaps, holes or other specific leaks in any substrate

Proceed as with repairing a crack in a plastic tank except don’t drill any holes at each end of the crack.(If there is one)

In so far as exterior surfaces are concerned work on the outside of the surface.

Remember to make sure any substrate onto which you are going to work must be clean and dry.

Three important rules top remember in coatings are preparation, preparation, preparation.

 

General waterproofing. (Metal, asbestos, tiles, concrete, plastic etc.

Onto any surface that is porous or leaking, first clean the entire substrate and make sure it is dry before applying the first coat of Aqua-

Mite mixture (Two parts of powder to one part of liquid by volume.)

Coat by brush or roller application the whole surface with brush or roller movements

in one direction.  A second coat of Aqua-Mite is then applied after the first has had a chance to dry by applying with brush or roller

at a 90 deg. angle to the first coat. 

Don’t work if it is going to rain or if the surface is wet.

Do dampen with water any concrete surface slightly before applying any mixed Aqua-Mite. Clean equipment with ordinary water.

MIXING WITH AQUA-MITE FLUID

Mixing procedure for mortars or concretes containing Aqua-Mite Fluid is similar to that used for conventional compositions, gauging water being partly or completely replaced by Aqua-Mite Fluid.  The quantity of Aqua-Mite Fluid recommended will depend upon the application and is normally from 9 to 18 litres per 50 kgs of cement.  The higher level of Aqua-Mite Fluid addition is used for thin screeds where maximum performance is required ; levels lower or higher than those quoted may be used in special circumstances.  The colour of Aqua-Mite Fluid-modified compositions may be a little darker than that of ordinary compositions; if this is undesirable it can be simply remedied by including a proportion of white cement.

 

Typical examples of mortars are given in the appendix.

 

Portland, High Alumina and certain fast setting cements are compatible with Aqua-Mite Fluid and have been successfully used.

 

Water/cement ratio

Mortars containing Aqua-Mite Fluid will have a water/cement ratio slightly lower than that for conventional mortars.

 

Aggregate

Washed sharp sand, free from excessive fibres, should always be used in Aqua-Mite Fluid-modified cement mortars.  Where a very smooth surface is required a fine sand may be used, but it is important to ensure that there are no very fine clay-like particles present.  Many types of aggregate have been successfully used in Aqua-Mite Fluid modified compositions; typical examples are those conforming to the SABS 1090 - 1976 “Sand for plaster and mortar” as well as granite chippings used in heavy duty flooring.

 

Workability

The workability time is generally slightly increased by the addition of Aqua-Mite Fluid.  In cold weather conditions (ie below 10º C) especially when it is also damp, it is desirable to use a rapid or extra-rapid hardening cement.  Alternatively, ordinary Portland cement may be used in conjunction with 2% - 4% of calcium chloride (expressed on cement weight); the calcium chloride should be added as a 50% solution in water to the mortar mix.

 

Additives

Workability additives such as fly ash and lime are not necessary as Aqua-Mite Fluid exerts a considerable plasticising effect of it’s own.  Air entraining agents should not be used without adequate testing.  The addition of an anti-foaming agent may sometimes be desirable and we have found that Nopco NDW added at the level of 20g per 5 litres of Aqua-Mite fluid is an effective material.

 

Cleaning of equipment

All tools should be cleaned immediately after use because hardened Aqua-Mite Fluid-modified cement compositions have excellent adhesion and are therefore difficult to remove.  If this important precaution is overlooked, solvents such as white spirit, solvent naphtha or preferably toluene can be useful in removing hardened Aqua-Mite Fluid-modified mortar.

 

Note on anti-foam

For most applications, addition of anti-foam is not normally necessary when using Aqua-Mite Fluid.  Occasionally, it may be desirable to incorporate an anti-foam in some Aqua-Mite Fluid-modified flooring compositions, eg those containing flint aggregates.  If anti-foam is required, we suggest the addition of Nopco NDW added at the level of 14 g antifoam per 5 litres.

APPLICATION OF AQUA-MITE FLUID

The next section of this bulletin gives detailed information describing the use of Aqua-Mite Fluid modified compositions for walls and floors.  Also included are some recommendations for water-resistant treatments, patching and heavy-duty floorings.  We have extensive knowledge of the use of Aqua-Mite Fluid in a host of specialised applications, and we are always pleased to make recommendations for individual requirements.

 

Test results obtained on Aqua-Mite Fluid-modified compositions are given in separate test data sheets.

 

WALL RENDERINGS

Preparation

It is necessary to ensure that the wall surface is free from crumbly or other unsound areas.  Dusty patches and old paint should also be removed.  It is usually sufficient to prepare the wall with a wire brush.  All surfaces should be dampened an hour or so before priming.

Priming

The application of a priming coat is normally recommended to obtain maximum adhesion of the subsequently applied rendering.  The priming coat, consisting of 2 parts or ordinary Portland cement slurried with 1 part of Aqua-Mite Fluid, should be thoroughly brushed on to the prepared wall surface.

The renderring is applied whilst the mixture is still wet.

Mixing

A general purpose rendering compositions is as follows :-

            SABS 1090 - 1976 “plaster sand”        100 kgs

            ordinary Portland cement *                     33 kgs

            Aqua-Mite Fluid                                   6 litres

            water                                                    as required to adjust consistency

* see earlier remarks regarding the use of rapid hardening cements or calcium chloride in   cold weather conditions.

 

NOTE    Although fine sand may be used, especially where a very smooth surface is required, it is essential that there should be no ultra fine clay-like material present in the sand.

 

Mixing should preferably be carried out in a concrete mixer, although hand mixing is permissible where the total weight of the dry batch does not exceed 50 kgs.  The usual procedure is to quickly pre-mix the sand and cement in a mixer, pour in the Aqua-Mite Fluid, mix for 2-3 minutes and finally cautiously add water little by little until the required consistency is achieved  over addition of water causes rapid thinning of Aqua-Mite Fluid modified mortars owing to the plasticising effect of the Aqua-Mite Fluid.

 

Application

The thickness of Aqua-Mite Fluid-modified renderings should be restricted to not more than approximately 6mm for each coat.  Greater thickness tends to cause sagging or, in the case of soffits, actual fall off of the unset renderings.  However, several coats may be applied in fairly rapid succession; it is sufficient to allow each coat time to set-off adequately to receive the subsequent coating.  The time required between coats will vary according to conditions but is typically 15 - 30 minutes.

 

A single trowelling operation is usually sufficient  to achieve a moderately smooth finish.  If a smoother surface is required, the rendering should be floated using a clean steel or preferably wooden float after a suitable interval has elapsed.  This interval is usually about ½  to 1 hour, but is best found by experience.

 

WATER RESISTANT RENDERING

Where the main requirement of the rendering is improved water resistance, a modified application technique is recommended.

 

After preparing the substrate as described above, two sealing coats consisting of approximately two parts of Portland cement slurried with 1 part of Aqua-Mite Fluid should be thoroughly brushed on to the surface.   The second sealing coat may be applied as soon as the first coat is touch dry, ie after approximately 20 to 30 minutes.  Ideally, the sealing coats should be applied at right angles across each other, thus ensuring complete coverage of the substrate.

 

It is emphasised that the thickness of each sealing coat should not exceed 1.6 mm otherwise crazing may occur.  Before proceeding further, the double sealing coat system must dry out completely for a period of at least 48 hours.

After the sealing coats have dried thoroughly, a tack coat consisting of two parts Portland cement slurried with one part of Aqua-Mite Fluid should be applied.  The renderings should then be applied whilst the tack coat is still wet.

 

The amount of Aqua-Mite Fluid required in the rendering composition depends upon the degree of water resistance required and the conditions prevailing during application, but the addition of 14 litres of Aqua-Mite Fluid per 50 kgs of cement is usually satisfactory.  Where high hydrostatic pressures are anticipated, the level of Aqua-Mite Fluid normally recommended is 20 litres per 50 kgs of cement.

 

Because the application of water-resistance rendering is a specialised procedure, we advise each customer to consult us for recommendations appropriate to his individual requirements.

 

FLOOR SCREEDS

 

Preparation

Where the existing floor is old or dirty, it is essential to remove all contaminant such as oil, grease, paint etc to ensure adequate development of bond when the topping is applied.  Any unsound crumbly concrete must also be removed.

 

An efficient way of preparing an old floor is to use a mechanical scabbler to remove all unsound materials.  If the concrete is in reasonably good order light scabbling will suffice, eg to a depth of about 2 - 4 mm.

 

For new floors, to which for example a levelling screed needs to be laid, it may still be desirable to remove the upper surface to ensure that weak surface latence is not present.  Light scabbling to a depth of up to 4mm will normally suffice.  Alternatively good results can often be obtained by etching either new or old concrete floors with hydrochloric acid (1 part of concentrated acid diluted with 2 parts of water) followed by a thorough washing to remove all traces of acid.

If screed bars are to be used to define thickness of the screed, these should be positioned after the above preparation.

 

Priming

The application of a priming coat is normally recommended to obtain maximum adhesion of the subsequently applied screed.  The prepared floor should be thoroughly dampened with water, hosing is suggested, followed by removal of excess standing water.  A priming coat, consisting of 2 parts of ordinary Portland cement slurried with 1 part of Aqua-Mite Fluid , would then be thoroughly brushed into the floor using a stiff broom.  The topping is applied whilst the priming coat is still wet. 

For general-purpose topping, the following composition is suggested :-

 

SABS 1090 - 1976 “mortar sand”        100 kgs

Ordinary Portland cement                     33 kgs

Aqua-Mite Fluid                                   6 litres

Water                                                   as required to adjust consistency

The mixing procedure is straight forward, and is as described in the section dealing with wall renderings.

 

Application of topping

Screeds based on the above composition can be laid to any thickness, down to a featheredge if necessary, providing that a sufficiently find grade of sand is used.    However, it is essential that there should be no ultra fine clay-like material present in the sand.

 

Because Aqua-Mite Fluid allows “feather-edging” of suitable mortar compositions, it is therefore possible to patch up only the damaged portions of existing concrete floors.  These portions must, of course, be prepared and primed as previously described.

 

After mixing the Aqua-Mite Fluid, mortar should be poured over the still wet priming coat and struck off.  It may then be trowelled to the required finish.  An experienced floor layer will readily achieve a finish of satisfactory smoothness without having to do any further trowelling.  However, as an alternative procedure it is possible with care to carry out further trowelling after a suitable interval, when initial stiffening of the mortar has commenced.  A clean steel trowel is recommended for this operation.

 

With a little experience, the correct timing at which this retrowelling should be carried out will be properly judged.  If insufficient time has been allowed to elapse, a thin surface skin will be present over soft unset material and the skin will be torn giving surface cracking.   Too great a time interval on the other hand would result in the mortar having set too much to be smoothed.  The whole surface should be trowelled, not just sections of it to avoid variations in shade, texture, etc.

 

Heavy duty flooring

Aqua-Mite Fluid may be used with advantage in heavy duty flooring compositions.  The procedures for preparing and priming the existing floor and for mixing and application is as described for general purpose floor screeds.

 

Aqua-Mite Fluid modified heavy-duty floorings are normally laid as 12 mm toppings.  An exception to this is the iron aggregate flooring, which we recommended laying as a 6 mm topping.

 

A typical heavy-duty composition is as follows :-

 

Portland cement                                                100 kgs

SABS 1090 - 1976 “mortar sand”                    125 kgs

3mm granite chippings                           125 kgs

Aqua-Mite Fluid                                               18 litres

Water                                                               as required to adjust consistency

Summary of results

The control samples had adhesion values between 0 and 350 kp depending upon test conditions. Incorporation of Aqua-Mite Fluid markedly improved adhesion to concrete, even at low levels of addition; the advantage of using this Aqua-Mite Fluid under both dry and wet conditions are clearly illustrated.

 

These results give definite indication of the benefit of using Aqua-Mite Fluid as an admixture to cement for flooring screeds, wall renderings and adhesive layers.

SHRINKAGE OF CEMENT MORTARS DURING THE DRYING PROCESS - EFFECT OF AQUA-MITE FLUID ADMIXTURES

 

Test method

 

To test for shrinkage on setting, a mild steel mould 25 cm long x 2,5 cm wide x 2,5 cm deep was used, and the inner surfaces of the mould were lightly smeared with petroleum jelly before filling with mortar.  The mortars under test were tamped down, levelled and left to dry for 28 days at room temperature.  The longitudinal shrinkage of the mortars was measured at the end of this period using a travelling microscope.

 

All mortars testes were based on 3 parts BS 12 sand and 1 part Portland cement.  Control samples without admixture were compared with mortars containing various levels of Aqua-Mite Fluid

EFFECT OF HEAT AGEING UPON PHYSICAL PROPERTIES OF CEMENT MORTARS

 

Introduction

 

Heat ageing tests are employed to obtain data, which have a bearing on long-term performance.  A general guide used in the rubber industry is that one week at 70ºC approximates to 5 years of normal service life.

 

Test method

Cement mortars were prepared based on 3 parts BS 12 sand and 1 part of Portland cement.

 

Control

no admixture

Aqua-Mite Fluid

as admixture at 40 parts per 100 parts cement by weight

all acrylic

as admixture at 40 parts per 100 parts cement by weight

 

Flexural strength was evaluated on “wet-cured” test pieces which had been treated as follows :-

 

1 day drying + 6 days immersion in water + 21 days drying, prior to ageing.

 

Adhesion to concrete was measured on “dry-cured” samples because wet curing can lead to unreliable results in this test.  The test samples were simply dried for 28 days before ageing and testing.

 Summary of results

The tests show that Aqua-Mite Fluid retains its effectiveness in cement mortar compositions over long periods of heat ageing, showing marked improvements over unmodified samples.  It compares favourably with the all-acrylic polymer.

 

Aqua-Mite Fluid may therefore be expected to remain effective throughout the normal service life of cement compositions treated with it.

AQUA-MITE FLUID TEST DATA SHEET NUMBER 6

 

RESISTANCE TO WATER PENETRATION OF CEMENT COMPOSITIONS CONTAINING AQUA-MITE FLUID

 

Scope

 

Two distinct water-resistant treatments using Aqua-Mite Fluid were evaluated viz :-

 

1.         A Aqua-Mite Fluid/cement slurry sealing coat system sandwiched between two layers of conventional cement mortar.

 

2.         Cement mortar, based on 3 parts of sharp sand to 1 part of Portland cement, using various levels of Aqua-Mite Fluid as admixture.

 

Test method

Preparation of samples

 

Annular, mild steel bands (85mm internal diameter and 15mm depth) were used as moulds for the mortar test samples.  Methods of preparation of the two sets of samples are described below :-

 

1.         Aqua-Mite Fluid/cement sealing coats as a water-resistant treatment

            Moulds were filled to half depth with a conventional cement mortar (3 parts of sharp sand to 1 part of Portland cement) and left to dry for 3 days at 20ºC.

 

            After 3 days, a sealing coat consisting of 2 parts of Portland cement slurried with 1 part of Aqua-Mite Fluid was brushed on to the upper surface of the dry mortar, ensuring that all brush stroked were made in the same direction.  After 1 hour, a second sealing coat was applied with brush strokes at right angles across the strokes of the first coat.

 

            The coated test pieces were allowed to dry for various periods of time : 24, 48 and 72 hours.

 

            A third coat of fresh slurry was then applied as an adhesive tack coat.  Whilst the third coat was still wet and tacky, a conventional mortar (3 parts of sharp sand to 1 part of Portland cement) was placed on the tack coat, filling the remaining half of the mould.  The “sandwich” test pieces thus obtained were allowed to dry for 7 days at 20ºC prior to testing.

 

 

2.         Aqua-Mite Fluid as a water-resistant admixture in the mortar

 

            Cement mortars, based on 3 parts of sharp sand to 1 part of Portland cement, containing respectively 0, 20, 30 and 40 parts of Aqua-Mite Fluid per 100 parts of cement were prepared.  Annular moulds, as described above, were completely filled with each composition.

 

The mortars were allowed to dry for 7 days at 20ºC    prior to testing.

 

Testing

 

Each mortar disc, retained in it’s mild steel band, was clamped into a test apparatus designed to apply water pressure, equivalent to a 30 metre head of water, to one face of the disc.  The other face (ie the underside) of the disc was open to the atmosphere.

 

Throughout the test, a constant water pressure was maintained, and the water pressure gauge monitored for any reduction in pressure.   Pressure drop, which in this test indicated sample failure, was corrected where necessary.  Any water which did pass through was collected in a measuring cylinder and the volume recorded.

 

Testing was continued until either a measurable volume of water passed through the sample, or where no water penetrated, for a period of 3 weeks.  On completion of the test, the underside of each sample which withstood 3 weeks testing was carefully examined to ensure that there was no sign of water penetration.

 

Details of the test apparatus will be supplied on request.

 

Results

 

Results, expressed in mls of water passing through the samples, are shown in the following tables :-

Summary of results

 

The results of these tests show that the following treatments provide effective water resistance for cement mortars :-

 

1.         Two sealing coats plus one tack coat using Aqua-Mite Fluid /cement slurry

            Portland cement (2 parts) is slurried with Aqua-Mite Fluid (1 part) and two coats of the slurry are applied at right angles across each other on the surface to be treated.

 

            Following this, at least 48 hours drying is allowed, and then a fresh slurry of cement and Aqua-Mite Fluid is applied at a tack coat for the surfacing mortar.

 

2.         Mortar modified with Aqua-Mite Fluid

 

            40 parts of Aqua-Mite Fluid per 100 parts of cement gives a water-resistant mortar (3 parts sand to 1 part of cement) using a suitable sand.

 

            For optimum results, the system of two sealing coats plus one tack coat of Aqua-Mite Fluid/cement slurry (1) may be combined with the Aqua-Mite Fluid modified mortar (2); see alto Technical Bulletin No GEN TB25 page 3.

 

            Because water-resistant treatments are specialised procedures, we advise each customer to consult us for recommendations appropriate to his individual requirements.

FREEZE-THAW RESISTANCE OF CEMENT MORTAR BLOCKS - EFFECTS OF AQUA-MITE FLUID

 

Test method

 

Test pieces were prepared from mortars based on 3 parts BS 12 sand and 1 part of Portland cement.  Aqua-Mite Fluid was used at the level of 40 parts Aqua-Mite Fluid to 100 parts cement ( by weight) and compared with controls without admixture.  All test pieces were dried for 24 hours, immersed in water for 7 days, then dried for 21 days before testing.

 

The samples were frozen in a 10% aqueous solution of sodium chloride - this was chosen in preference to water to accelerate deterioration.   Each freeze-thaw cycle was as follows :-

 

Frozen for 20 hours in a 10% sodium chloride solution at -18ºC.

 

Thawed and examined.

 

Test pieces were subjected to a number of freeze-thaw cycles, allowed to dry out, then tested for flexural strength.

CO-EFFICIENT OF LINEAR EXPANSION OF CEMENT MORTAR BLOCKS - EFFECT OF AQUA-MITE FLUID

 

Test method

 

Cement mortars, based on 3 parts of sharp sand to 1 part of Portland cement, were prepared for the test.  Control samples were compared with samples containing Aqua-Mite Fluid (added at the level of 30 parts Aqua-Mite Fluid per 100 parts of cement).

 

Mild steel moulds, 10,7cm long x 5cm deep were constructed for the test and the linear surfaces lightly smeared with petroleum jelly before filling with mortar.  The mortars under test were tamped down, levelled and removed from the moulds after 24 hours drying.  The test pieces were then cured by immersion in water for 3 days followed by drying for 24 days before testing in the laboratories of an independent group of testing engineers and consultants.

 

The co-efficient of linear expansion was determined in the following temperature ranges :-

 

                1.            - 20°C to + 20°C

            2.         +20°C to + 60°C

EFFECT OF TEMPERATURE ON THE WORKABILITY TIME OF CEMENT MORTARS CONTAINING AQUA-MITE FLUID

 

Test method

 

Mortar compositions based on 3 parts of BS 882 Zone 2 sand to 1 part of cement were prepared for the test.  Aqua-Mite Fluid was included as admixture at the level of 40 parts Aqua-Mite Fluid per 100 parts cement by weight, and the water/cement ratio adjusted to 0.31-.  Mortars were prepared using two different types of cement.

 

·                    Ordinary Portland cement

·                    rapid hardening cement

 

The workability time of each type of cement mortar was assessed at various ambient temperatures within the range 1 to 32°C.

 

Results are shown in the graph overleaf.

 

Summary of results

 

Aqua-Mite Fluid-modified cement mortars were found to have practicable workability times at temperatures ranging from about 30°C down to 20°C.  Ordinary Portland cement gave satisfactory results at temperatures down to 7°C, whereas rapid hardening cement was more suitable for the low temperature range, ie 2 - 7°C.

 

The British Standard Code of Practice CP114: Part 2 : 1969 recommends that concreting should not be carried out unless “the concrete has a temperature of at least 4°C and that the temperature of the concrete is maintained above 2°C until it has thoroughly hardened”.  Similarly we would not recommend the application of Aqua-Mite Fluid-modified mortars and concretes unless the above recommendations can be met.  When applying the modified mortar or concrete at temperatures between 2 and 10°C, a rapid hardening cement should be used.

Test details

Four test samples 12 x 12 x 1¼“ of each mix were prepared by normal techniques, using reasonable vibration by rodding and mould wall tapping.  The samples were covered with dry burlap (hessian-like material) and polythene sheet for 24 hours.  Samples were then de-moulded and cured for a further 19 days at 70+ 2°F at 50 ± 5% relative humidity.

 

The top surface of the cured samples was dry abraded by grinding or sandblasting to reduce the height by 1/16 - 3/16”.  Dams, 3/4” high by 1/2” wide were placed around the top edges of three of each set of four samples.  The three samples were covered with 1/2” of 3% aqueous sodium chloride solution.  During ‘ponding’ the samples were kept at 70 ± 2°F and 50 ± relative humidity.

 

At the end of 90 days, the solution was removed.  After drying the surfaces of the samples were wire brushed until all salt build-up had been removed.

 

Three samples of concrete were taken from each specimen (including the ‘unponded’ ones) by dry coring (1½“ minimum diameter) and the cores cut to obtain specimens.

 

A.        1/16” - ½“ depth from the surface and

B.         ½“ - 1” depth from the surface.

 

These sections were crushed and analysed for chloride content.  The average value obtained from the ‘unponded’ samples was subtracted from the average value obtained from the ‘ponded’ samples, and the result expresses as pounds of chloride (CI) per cubic yard of concrete.  (Although not yet officially specified, a maximum acceptable value of chloride in the  ½“ to 1” depth is less than 1.2 lb of chloride per cubic yard.  Usual values in the 1/16” to  ½“ depth sections are 5 to 9 lbs of chloride per cubic yard).

 Mix design

 

The mix design used in the tests was as follows :-

 

                                                            lbs

Portland cement - type 1                       94

Concrete sand                                      275

Coarse aggregate, 8                              180

Aqua-Mite Fluid                                   29,4

 

Water : added as required to give water/cement ratio of 0,40 with a slump of 4-6” and air content of less than 6%.

 

Control mixes (no Aqua-Mite Fluid ) were made with water/cement ratios of 0.40 and 0.50.

 

Concrete sand gradation was :-

 

100%                           smaller than 12,5 mm

85 - 100%                              “         9,5 mm
