【英文摘要】 Rubber,polypropylene fiber and steel fiber were used by different combinations to reinforce the high strength concrete.The compressive strengths of reinforced concrete at room temperature and high temperature were tested.The effects of different combinations of three kinds of material on compressive strength and ductility of reinforced concrete at room temperature and high temperature were investigated. Test results show that the spalling resistance of high strength concrete is greatly improved by
