Experimental study on the influences of fly-ash and slag on the plastic shrinkage of concrete

Fly-ash and slag are the commonly used concrete admixtures, and can improve the durability of concrete.In this paper, the influence rules of different contents of fly-ash and slag on the workability and the capacity of resisting plastic shrinkage of concrete were investigated through a series of experiments.The results showed that adding fly-ash and slag to concrete can improve the workability of concrete, and the area of plastic cracking was smallest with addition of 20% fly-ash and slag.The achievement of the experimental study of the article may provide some references for making anti-shrinkage concrete.
