POLY-CARBOXYLATE SUPERPLASTICIZER
1. Application
Poly-Carboxylate is a superplasticizer for high performance concrete, high strength concrete, high volume fly ash/slag concrete and grouting/self-leveling screed/mortar.

2. Characterstic
1） 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.

3.Technology
Poly-carboxylate-based water reducer is a kind of superplasticizer emerged in the early 80& acute; 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 compound 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.
