Abstract：Rubber powder,steel fiber and early strength agent were chosen as the three test factors to set the two orthogonal experiment groups and the ordinary early strength concrete was the control group. Based on the optimum contents from the orthog-onal experiment,the compressive strength,flexural strength,crack resistance and abrasion resistance of the optimum groups' were compared with that of the ordinary early strength concrete. The results indicate that,when the volume fraction of steel fiber is be-tween 0.25% and 0.75% and the content of rubber powder is between 5% and 9%,the optimum contents are 0.5% and 5% re-spectively;when the volume fraction of steel fiber is between 0.75% and 1.25% and the content of rubber powder is between 1% and 5%,the optimum contents are 1.25% and 3% respectively;taking into comprehensive consideration of bearing capacity,service-ability,economic benefit and practicability,the suggessted volume fraction of steel fiber is 1.00%~1.25%,the best contents of early strength agent and rubber powder are 12%~15% and 3.0%~3.5% respectively.
