It has multiple effects such as high water reduction rate, low shrinkage rate, and excellent fluidity. It can improve the workability of concrete, especially the viscosity of concrete, reduce the probability of cracking, and has no adverse effect on the mid- and late-stage strength of concrete.

Ultra-high strength concrete, compressive strength in the range of 80~150MPa, such as foundation concrete, concrete for wind power construction, ultra-high performance concrete, bridges, etc. Concrete that requires high strength. Not suitable for concrete with strength less than 50MPa.
