1.water reducing, high early strength, and high permeability enhancement
2..slow down the speed of hardening cement .

         this product is compounded by high-efficient water reducing admixture and various retarders. It not only keeps the high-efficient water reducing admixture’s early strength and high strength sex, but also plays the role of slowing down the speed of hardening cement.

This product meets GB8076-1997 quality standard.

 

Homogeneity index

Test items	index
Appearance	Light brown powder
Solid content  %	>90
Chloride ion content %	<1
Fluidity of cement paste mm	>180  mm
Fineness(0.315 mm screen residue)	<15

Main performance:

the dosage is 0.6%~1% of the cement content ,water reducing ratio is up to 14%~22%No effect on early strength.Quan condense time can be extended by2-4 hours. Extending or shorting is available for special requirements.Heat time can be delayed; peak heat should be reduced in case of crack.
