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. 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 waterproofer® Fluid.

Results

Summary of results

In formulating Aqua-Mite waterproofer® Fluid for admixture to cement, one of the properties, which have been optimized, is resistance to shrinkage during setting of the modified cement.

The above test results show that Aqua-Mite waterproofer® Fluid gives a great improvement in resistance to shrinkage – this is in accordance with qualitative observations on large areas.

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 waterproofer® 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.

RESULTS

Heat ageing at 70ºC

Summary of results

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

Aqua-Mite waterproofer® Fluid is therefore 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 :-

An Aqua-Mite waterproofer® Fluid/cement slurry sealing coat system sandwiched between two layers of conventional cement mortar.

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

Test method and 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 :

Aqua-Mite waterproofer® 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 waterproofer® Fluid was brushed on to the upper surface of the dry mortar, ensuring that all brush stroked were made in the same direction. within 1 hour, a second sealing coat was applied with brush strokes at right angles across the strokes of the first coat.

What next

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.

Aqua-Mite waterproofer® 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 waterproofer® 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 ml’s of water passing through the samples, are shown in the following tables :

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

Note

The conventional cement mortar compositions used to “sandwich” the Aqua-Mite waterproofer® Fluid/cement sealing coats tested above were based on BS 882 Zone 2 sand.

Another conventional mortar composition, based on BS 12 sand, was also used in these experiments. Here, the sealing coat system was tested after 72 hours drying only. Again, no water penetrated after 3 weeks.

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

Note

These mortar compositions were prepared using BS 882 zone 2 sand. Another composition, based on BS 12 sand and containing 40 parts of Aqua-Mite Fluid per 100 parts of cement was also tested. No water penetrated after 3 weeks.

Summary of results

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

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

Portland cement (2 parts) is slurried with Aqua-Mite waterproofer® 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.

Mortar modified with Aqua-Mite Fluid.

40 parts of Aqua-Mite waterproofer® 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 waterproofer® Fluid/cement slurry (1) may be combined with the Aqua-Mite waterproofer® Fluid modified mortar (2); see alto Technical Bulletin No GEN TB25 page 3.

Because water-resistant treatments are specialized 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 waterproofer® 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.

Results

The results are compared with figures obtained on samples not subjected to freeze-thaw treatment :-

Summary of results

The control samples could not be tested for flexural strength after more than 15 freeze-thaw cycles because of severe deterioration.

On the other hand, the Aqua-Mite waterproofer® Fluid modified test pieces showed no visible signs of deterioration after 60 cycles, thereby confirming the efficiency of Aqua-Mite waterproofer® Fluid in combating freeze-thaw damage to concrete.

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 waterproofer® 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. 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.

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

1. – 20°C to + 20°C

2. + 20°C to + 60°C

Results

Results obtained are shown in the following table :

EFFECT OF TEMPERATURE ON THE WORKABILITY TIME OF CEMENT MORTARS CONTAINING AQUA-MITE waterproofer® 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 waterproofer® Fluid was included as admixture at the level of 40 parts Aqua-Mite waterproofer® 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 waterproofer® 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”.

Our opinion

Similarly we do not recommend the application of Aqua-Mite waterproofer® 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.

AQUA-MITE FLUID CEMENT ADMIXTURE IN MODIFIED CONCRETES WHERE RESISTANCE TO SALT (SODIUM CHLORIDE) SOLUTIONS IS REQUIRED

Test results

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. These 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. Then 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.

After 90 days

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 ‘un-ponded’ ones) by dry coring (1½“ minimum diameter) and the cores cut to obtain specimens.

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

2. ½“ – 1” depth from the surface.

These sections were crushed and analyzed for chloride content. The average value obtained from the ‘un-ponded’ 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 :

In lbs

Portland cement – type 1 94.

Concrete sand 275.

Coarse aggregate, 8 180.

Aqua-Mite waterproofer® 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.

10 – 30% “ 4,75 mm.

0 – 10% “ 2,36 mm.

Coarse aggregate (8) gradation was :

100% smaller than 9,5 mm.

95 – 100% “ 4,75 mm.

80 – 100% “ 2,36 mm.

50 – 85% “ 1,18 mm.

25 – 60% “ 0,06 mm.

10 – 30% “ 0,03 mm.

2 – 10% “ 0,015 mm.

Conclusion

Aqua-Mite waterproofer® Fluid gave very good results in these tests showing a great improvement compared with the controls and has been approved by the US Federal Highway Administration for use in Highway Systems, particularly in bridge decking.

It may also be recommended for use in other concretes and mortars where protection from salt erosion or damage is required.
