Investigation for Influence of Pulverized Slag,Expanding Agent and Fiber on Anti-cracking Performance of Cement Concrete

LIU Ying1,XUE Xin2,HAO Zengheng1,ZHANG Yi3  
This paper investigates the influences of pulverized slag,expanding agent and fiber on mechanical properties,shrinkage properties and internal structure of cement concrete via indoor test and microscopic test,respectively.The results of investigation show that the pulverized slag and expanding agent can improve the compactness of concrete and prevent early cracking;the fiber disperses in concrete and forms a 3-dimensional network supporting system so as to increase the ductility and enhance crack resistance of concrete;and the concurrent use of these three materials plays a complementary action for concrete performance.
