Admix WP763

Waterproofing Admixture for Concrete and Cement Based Mortar


ADMIX WP763 is a powder form admixture with double performance in concrete and cement based mortar
– Powder form superplasticizer causes reduction of water and leads to less voids. Water cement ratio should be considered at lower rate, and be calculated at about 40%.
– Waterproofing powder in reaction with water forms water repellent material and which prevent ingress of water.

Where to use

ADMIX WP763 is used for production of watertight concrete structures such as water convey channels, lining of tunnels and galleries, water reservoirs (potable and industrial water), swimming pools, waterfalls, lakes, foundations and facades.

Technical Properties

Appearance: Cream powder
Color: Milky white
Bulk density: 1.02 – 1.03 g/cm³
Chloride content: < 0.1% w/w
Air entrainment: < 1%

Application method
ADMIX WP763 should be added at the last stage of concrete production. Never add this product to dry materials. If concrete is carrying to the site by truck mixer, the admixture can be added to the truck and be mixed for 2 minutes by high speed rotation. As this product contains superplasticizer, the effect of admixture is observable in truck.

In case of workability lost due to delay in concrete placing, reusing of admixture or adding liquid superplasticizer is recommended based on remainder of cement in the truck to compensate workability lose.

Important note
Effect of this admixture is on fresh concrete although it results in waterproofing of hardened concrete, but if any cracks or cold joints appear during hardening process, it causes further leakages. Then these areas should be treated with ADMIX WP760 as surface waterproofing material.

Dosage of 1.5% to 2% of cement content is necessary for waterproofing of concrete; overdosing due to workability lost is 1% of remainder cement.

ADMIX WP763 is supplied in 20 kg PP bags.

ADMIX WP763 should be stored in original packages on pallets and be protected from sunlight, compaction and moisture. Shelf life of the products is 12 months.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product. For specific storage condition contact Damavand Sefid Technical Services Department.
