Cement mortar: hpmc​ improve the dispersion of cement sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks and enhance the strength of cement.

1. High water reduction rate: it has excellent water reduction rate and plasticity, and it still has excellent water reduction performance at low dosage, especially in cement-based mortar, gypsum based mortar and high-grade concrete, with a high water reduction rate of 40%;

Polycarboxylate superplasticizer is a concrete admixture with high water reducing rate and low slump loss.
