Influence of Steel-fiber Long-diameter Ratio on Bending Strength of Steel-fiber Polymer Concrete

The influence of long-diameter ratio of steel-fiber on bending properties of the steel-fiber polymer concrete was studied using single-point loading method.An appropriate amount of steel-fiber could improve the bending strength and toughness of the polymer concrete;When long-diameter ratio was 70 and quantity contained was 48kg/m3,the bending strength of steel-fiber polymer concrete was the biggest and the toughness was the best.
