Products Description
Polycarboxylate Superplasticizer PCE is the best example of polycarboxylate water reducer. Polycarboxylate water reducer has attracted more and more attention from modern construction industry because of its excellent dispersibility and retention.
Appcation
The Polycarboxylate Superplasticizer PCE is suitable for the preparation of precast concrete, cast-in-place concrete, fluid concrete and self-compacting concrete.
Especially suitable for low-grade commercial concrete.
Characterics
1. High early strength and ultimate compressive strength
2. Low slump loss: Great reduction of slump loss.
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.
