- Synopsis
- Since high strength and high flowable concrete is usually prepared at so low water/binder ratio and it contains high amount of powder, autogenous shrinkage and hydration heat are tend to be increased. For taking measure to this problem, in this study, high strength and high flowable concrete prepared adding both of expansive additive and shrinkage-reducing agent was made. The physical properties of the concrete were examinedand and the resistance to be cracking was also confirmed.

- low heat type portland cement, expansive additive, shrinkage-reducing agent, thermal cracking, autogenous shrinkage
