Polycarboxylate Based Superplasticizer Powder in Concrete(MC-5023 Slump Retention Type)

Product Description:

Michem® polycarboxylate superplasticizer powder (MC-5021) is a polycarboxylate ether copolymer with a comb structure. The initial dispersibility of cement is general, but the dispersion retention ability is continuously improved with time prolonging, and the slump resistant performance is excellent, which gives the building material excellent workability and mechanical strength.
