Polycarboxylate (Polycarboxylate Superplasticizer) is a high performance water-reducing agent, is the use of concrete in a cement dispersant, it can be divided into two categories on the chemical, to the main chain of methacrylic acid, side chain carboxylic acid groups and MPEG (Methoxy polyethylene glycol), polyester type structure. Another main chain is polyacrylic acid side chain of Vinyl alcohol polyethylene glycol, polyether structure.

Polycarboxylate cement a strong dispersion, can greatly increase the flowability of cement mixing and concrete slump, while significantly reducing water consumption, significantly improve the workability of the concrete, small concrete slump loss. Can significantly reduce water consumption and thus significantly improve the strength of concrete at different ages.
