【Abstract】 The effects of different content of steel fiber and polypropylene fiber on the compressive strength and splitting tensile strength of HPC were contrasted. The mechanical properties changes of steel and polypropylene fiber reinforced concrete were analyzed. The results show that reasonable amount of fiber can increase the compressive and splitting tensile strength of HPC,especially for splitting tensile strength. Finally,according to the test results,the formula of compressive and splitting tensile strength of HPC with steel and polypropylene fiber is proposed.更多还原
