The Inhibitory Effect of Polypropylene Fibers towards the Shrinkage of Cement Based Material

Abstract:

At present, polymers, fiber and other additives are added to the cement based materials by researchers at home and abroad for the purpose of dealing with the difficult problems occur in practical application, such as low tensile strength, small ultimate elongation, remarkable brittleness, easy to crack and other issues. In this paper, the shrinkage deformation of cement based materials are classified into four types upon the analysis of shrinkage reasons, then the inhibitory effect and its mechanism of polymers fiber for cement based material are investigated.
