22.14 Integral Crystalline Waterproofing Admixture

(DSR ITEM 22.22 to 22.26)

22.14.1 Materials

Integral Crystalline Admix is one part cementitious powder consisting of hydrophilic chemicals such as

Portland cement, very fine treated silica sand and various active, proprietary chemicals. These active

chemicals react with the moisture in fresh concrete with the by-products of cement hydration to cause a

catalytic reaction, which generates a non-soluble crystalline formation throughout the pores and

capillary tracts of the concrete. Thus the concrete becomes permanently sealed against the penetration

of water or liquids from any direction. The concrete is also protected from deterioration due to harsh

environmental conditions.

22.14.2 Technical Specification/Parameters

The integral crystalline waterproofing admixture shall confirm to the following requirements:

1) At the manufacturers recommended dosage, (i) Material must fulfil the requirements of American concrete institute guidelines ACI-212-3R-

10, the coefficient of permeability should be measured for penetration of water. Under hydrostatic pressure of 72.5 psi (5 bars) to 150 psi (10 bars) for 72 to 96 hours as per DIN 1048 Part V. Reduction of water penetration should be 50 to 90%.

(ii) The performance of the crystalline admixture must not be restricted by water/cement ratio of the concrete mix. In other words, the crystalline admixture must perform at any water / cement ratio of the concrete mix.

2) The product has no corrosion effect on reinforcement steel according to test norm DIN V 18998. The maximum chloride content lies less than 0.1% and maximum alkali content less than 9.3%.

3) The integral crystalline admixture must be compatible with any other concrete admixture confirming to ASTM D494 and IS 9103.

4) It will not be affected by wear abrasion of the treated concrete surface and crystalline treated concrete shall not require protection layer.

5) The recommended crystalline admixture shall be non-toxic and shall confirm to NSF 61 USA. Note - The manufacturer shall produce relevant test certificates as per relevant code as stated above.

22.15 Integral Crystalline Slurry

22.15.1 Materials

Integral crystalline slurry is a surface-applied, integral crystalline waterproofing material, which waterproofs and protects concrete in-depth. It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. Integral crystalline slurry needs only to be mixed with water prior to application. When Integral crystalline slurry is applied to a concrete surface, the active chemicals react with moisture and the by-products of cement hydration to cause a catalytic reaction which generates an insoluble, crystalline structure. These crystals fill the pores and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). However, Integral crystalline slurry will still allow the passage of vapour through the structure (i.e. the concrete will be able to “breathe”). Even after the concrete has cured, Integral crystalline slurry remains dormant in the concrete and will reactivate in the presence of moisture to seal capillary tracts and hairline cracks. In addition to waterproofing the structure, Integral crystalline slurry protects concrete against seawater, wastewater, aggressive ground water and many other aggressive chemical solutions. Integral crystalline slurry is approved for use in contact with potable water, and is therefore suitable for use in water storage tanks, reservoirs, water treatment plants, etc. Integral crystalline slurry is not a decorative material. 25.15.2 Technical Specification/Parameters

22.16 Integral Crystalline Dry-Shake

22.16.1 Materials

Integral crystalline dry shake of hydrophilic in nature is a unique chemical treatment material for the waterproofing and protection of concrete. Integral crystalline dry shake has been specially formulated for dry-shake applications on horizontal concrete surfaces where greater impact and abrasion resistance is required. Packaged in the form of a dry powder compound, Integral crystalline dry shake consists of Portland cement, various active proprietary chemicals, and a synthetic aggregate hardener that has been crushed and graded to particle sizes suitable for concrete floors. Integral crystalline dry shake becomes an integral part of the concrete surface, thereby eliminating problems normally associated with coatings (e.g. scaling, dusting, flaking and delamination). The active chemicals react with the moisture in the fresh concrete causing a catalytic reaction, which generates a non-soluble crystalline formation within the pores and capillary tracts of the concrete.

Warehouse Floors Parking Structures

22.16.4 Directions for Application

22.16.4.1 Application Rates Under normal conditions, the coverage rate for Integral crystalline dry shake is 0.60 kg per sqm depending on the degree of abrasion resistance required. 22.16.4.2 Application Procedure Integral crystalline dry shake is to be sprinkled @ 0.60 kg per sqm over the PCC blinding, after fixing the reinforcement bars on the cured PCC so as to achieve positive side waterproofing below the raft concrete, as per the manufactures specification. 22.16.4.3 Curing Curing is important and shall begin as soon as final set has occurred but before surface starts to dry. Conventional moist curing procedures such as water spray, wet burlap or plastic covers may be used. Curing shall continue for at least 48 hours.

22.16.5 Precaution / Special Consideration For the best results when applying dry shake materials, the air content of the concrete shall not exceed 3% (a high air content can make it difficult to achieve a proper application).

In hot, dry, or windy conditions, it is advisable to use an evaporation retardant on the fresh concrete surface to prevent premature drying of the slab.

Chronic moving cracks or joints will require a suitable flexible sealant.

22.16.6 Storage / Shelf Life Integral crystalline dry shake must be stored dry at a minimum temperature of 45ºF (7ºC) and its shelf life is one year when stored under proper conditions.

22.16.7 Measurement

22.17 Crystalline Mortar

27.17.1 Materials

Crystalline mortar consists of Portland cement, specially treated quartz sand and a compound of active chemicals. The active chemicals react with moisture and the by-products of cement hydration to cause a catalytic reaction, which generates an insoluble integral crystalline complex. These crystalline complexes grow in the presence of water, block the capillaries of the concrete and minor shrinkage cracks, thus waterproofing it. Chemical activation begins when the powder is mixed with water and may take several days to completely block the capillaries depending on ambient temperature and environmental conditions.

i) Installation of seal strips, reglets and coves at joints to assure water tightness ii) Patching of tie holes and faulty construction joints

iii) Patching and filling of routed out cracks iv) Repairing of spalled and honeycombed areas

22.17.4 Surface Preparation All surfaces to be patched, repaired or sealed with crystalline mortar must be clean and sound. Cracks shall be routed out to a U-shaped configuration, approximately (20-25 mm) wide and a minimum of (20-25 mm) deep. Tie holes should be roughened prior to filling. Spalled and honeycombed areas must be thoroughly cleaned and chiselled back to sound concrete prior to repair. Remove all dirt, cement laitance, form release agents, curing compounds, paints, coatings, etc. by means of wet or dry sandblasting, high pressure water jet or other suitable mechanical means. Surfaces must be well moistened to a dull dampness at the time of application. The concrete should be damp with no wet seen on the surface.

22.17.5 Preparation of Material For routed cracks, coves and non-moving joints, add water to crystalline mortar until a medium stiff, trowelable consistency is reached. The texture of the mix should be pliable enough to be trowelled into the cracks with some pressure, but not so pliable that it would run out or sag out of the crack. Approximate mixing ratio (by volume) is 4.5 parts powder to 1 part water. Alternatively,100 ml of water to 450 gm of crystalline mortar powder. For tie holes and pointing applications, add only a small amount of water. Mixed consistency should be that of “dry earth”, holding a shape when squeezed in your hand but easily crumbled when pressed between fingers. Mix only as much material as can be used within 20 minutes.

22.17.6 Application 22.17.6.1 For sealing cracks and faulty construction joints, routed out/making U-shape groove size 25x25mm and then priming the surface with integral crystalline slurry @0.05 kg per running meter and while the surface is tacky filled the cavity upto surface crystalline mortar @1.50 kg per running meter.
