2high water reducing,the water reducing of this product can reach from 14-28%,can obviously improve the concrete every stage strengthphysical performance,especially for early strength,also can improve last strength,its compressiontensileanti-braking and elastic modulus.at same condition, it can save cement by 10-20%

3can obviously improve the cement materials workability and fluidity ,especially for slump retention.

4with less alkali content, can improve the concrete anti-permeability and anti-freezing

5this product has good adaptability for portland cementcommon portland cementslag cement and fly ash cement

6can get better performance for water reducing and slump retention by mixing with  aliphatic water reducing admixture and aminosulfonate admixture.
