We are engaged in manufacturing excellent quality Polycarboxylate Superplasticizer in Ningbo, Zhejiang, China.
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. Characteristic:-
1i High early strength: Significant increase of early strength and 28d strength.
2i Low slump lose: Great reduction of slump lose.
3i Excellent durability: Reduction of cracking , shrinkage and creep.
4i High water reduction: Water reduction more than 25% according to different application.
5i Environmental friendly products: Non pollution during production.

3.Technology
Poly-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 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.
