Principal Technical Performances:
1. Dosage amounts to *1.**2.5% of cementitious material, it can
reduce the unit water consumption by ****5%.
2. Incorporation of the product in keeping the same slump, it can
save ****5% of cement, the strength is not reduced.
3. Suitable for steam curing, the intensity increased rapidly, and
with the same slump and the same water consumption, the concrete
strength increases *****0% for 1 day, increased *****0% 3 days, and
increased ****0% 7 days.
4. There is still a corresponding increase in later strength of
concrete while mixing with this product.
5. Suitable for works *5 ℃ **0 ℃, it can accelerate the
progress of the templet and of the construction, it has a economic
and technical effects.
6. The product has neither retarder nor air-entraining, which has a
wide range of adaptability, it can improve the main mechanical
property of concrete and improve the impermeability performance of
concrete, but no effect on concrete shrinkage.
