(type WRA 2) Water Reducing Admixture For High Strength Cement & Concrete

Product Overview

Description

Type: WRA-2.

 

Recommended used quantity of Type WRA-2 Water-reducing Reinforcing Admixture:

0.1 to 0.3% of cement by weight.

 

Type WRA-2 Water-reducing Reinforcing Admixture has excellent water reducing performance, its water reducing ration can reach 20% -40% as per different added quantity. 

 

Type WRA-2 Water-reducing Reinforcing Admixture can cause concrete compressive strength (1 day) reaching 180% at normal temperature, and compressive strength ratio at 28d can reach 145%.

After using Type WRA-2 Water-reducing Reinforcing Admixture , the performances of tensile strength, breaking strength, permeability resisting, frost resistant, capability of bonding steel bar, carbonization resisting, all are improved effectively.

 
Mixing Type WRA-2 Water-reducing Reinforcing Admixture into steam-cured concrete, demoulded strength can be increase 40% or more. After steam-cured, the concrete strength at 28day can be increased about 20% , the steaming period can be reduced 1 / 3 or the temperature can be debased about 20 Degree C.

 

When mixing Type WRA-2 Water-reducing Reinforcing Admixture into the cement, and non-increasing the waterquantity, the slump constant of concrete can be reduced, and the strength does not fall.
