The water reduction rate index of retarded water reducing agent is the same as that of ordinary water reducing agent. The air content of concrete can reach less than 5.5%, which is wider than other water reducing agents. The setting time requirement should be delayed by at least 1.5 hours, and at most there is no requirement and can be stipulated in the production contract. The 3D compressive strength can reach the same as the benchmark concrete. The 28d acceptance strength is about 10% higher than the benchmark concrete.
Slow -coagulant water reduction agent is mainly used for the concrete formed by hot days, for pre -mixed concrete, for large -volume concrete, and can also be used for other concrete engineering that requires slowing coagulation. </p
