Effects of organic fiber and poloymer on the fatigue dam age perform ance of cem ent concrete

Organic fiber and polymer play important roles to improve the fatigue damage performance of cement concrete.In order to investigate the effect of organic fiber and polymer on the fatigue damage performance of cement concrete,the fatigue damage variables of organic fiber and polymer modified cement concrete were analyzed and optimized.Combined with the related research results of scholars at home and abroad,it expounds the particular process of fatigue damage and effects of organic fiber and polymer on the fatigue damage performance of cement concrete.Besides,based on the related experimental study,a suitable fatigue damage model for organic fiber and polymer modified cement concrete was explored,it could provide the basis for the rational design of organic fiber and polymer composite modified cement concrete.
