1  Used for and widely for self-cured, vaporcured concrete and its formulations. At the early stage of 

application, extremely prominent effects are shown. As the result, the modulus and siteutilization 

can be drastically, the procedure of vapor cureis omitted in peak-heat summer days. Statistically 

40-60 metric tons of coal willbe preserved when a metric ton of the material is consumed.

2 Suitable for preparation of early-strength, high-strength, high-anti-filtration and selfsealing& 

pumpable concrete.  

3 Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced 

concrete in key construction projects such as dam and port construction, road building & town planning 

projects and dwelling erections etc. 

4 Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement 

and Portland pozzolanic cement etc.
