Experimental Study on Plastic Shrinkage of Concrete

Plastic Shrinkage easily results in concrete crack. In this paper,effect of Concrete mix on plastic Shrinkage was studied. The experimental results show that plastic Shrinkage relate to water to cement ratio and there is critical water to cement ratio. When water to cement ratio is critical value,concrete has big plastic shrinkage. In addition,water quantity of concrete is bigger,plastic shrinkage of concrete is bigger when water to cement ratio is invariable.
