摘要：
摘 要：通过正交设计进行了钢/聚丙烯混杂纤维混凝土的坍落度和抗冲击强度试验，结果表明：钢/聚丙烯纤维混掺对混凝土的抗冲击强度增强显著，体现了不同弹性模量的纤维在不同层次上对混凝土的增强作用，找到了在试验条件下混杂纤维增强混凝土在满足抗冲击强度和工作性的较优组合配比。
Abstract:
Abstract: The experiment of steer/ polypropylene hybrid fiber reinforced concrete slump and resistance to impact is carried out through orthogonal design. The results show that hybrid fiber is remarkable for resistance to impact of concrete, which reflects that different elastic modulus fiber is different for resistance to impact of concrete at different phase，and the optimum mix proportion under the specific condition is found for hybrid fiber reinforced concrete.
