 POLY-CARBOXYLATE SUPERPLASTICIZER   OS-P GRADE

ApplicationPoly-Carboxylate is a superplasticizer for high performance concrete, high strength concrete, high  volume fly ash/slag concrete and grouting/self-leveling screed/mortar.

Characterstic1) High early strength: Significant increase of early strength and 28d strength.2) Low slump lose: Great reduction of  slump lose.3) Excellent durability: Reduction of cracking , shrinkage and creep.4) High water reduction: Water reduction more than 25% according to different application.5) Environmental friendly products: Non pollution during production.

TechnologyPoly-carboxylate-based water reducer is a kind of superplasticizer emerged in the early 80' s. It is mainly used in cement concrete. In chemistry, Poly-carboxylate-based is an organic and polymeric electrolyte. It belongs to a polymer surfactant. Therefore, it can also be applied in other paste materials such as gypsum products and ceramic products to reduce water content.Poly-carboxylate is a weak electrolyte. It can only be fully dissolved in an alkaline solution .It can complex with cations in cement/water system to control the cement hydration process and thus to reduce the slump loss of the concrete. Poly-carboxylate achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance when it is absorbed to the cement particles. Hence, Poly-carboxylate is the most effective superplasticizer for cement concrete.Poly-carboxylate is a raw material for superplasticizer. It is recommended that applicants should determine the Poly-carboxylate dosage in their own formulation according to their trial runs.

 Application Method1) Poly-carboxylate is used to produce high performance, high strength and flowable concrete.2) Dosage of Poly-carboxylate is determined according to the designated concrete mix through trial mixing.3) Poly-carboxylate is dosed either together with water or after the addition of water. It shows more effective when Poly-carboxylate is dosed after the addition of water.
