摘要: 为了改善活性粉末混凝土的力学性能，采用在活性粉末混凝土中混合掺加高模量的钢纤维和低模量的聚丙烯纤维的方法。通过两种纤维掺量的改变，研究二者混杂对活性粉末混凝土抗压强度、抗折强度力学性能的影响。从试验结果可以看出:两种纤维混杂使得活性粉末混凝土的力学性能得到一定程度的改善和提高。

Abstract: Two kinds of fibers i. e. steel fiber with high elastic modulus and polypropylene fiber with low elastic modulus,have been added to the reactive powder concrete(RPC) in order to improve its mchanical properties. In this paper,it is studied the impact of the change in the two fibers content on compressive strength and flexural strength of hybrid fiber reinforced PRC. The results indicate that the mechanical properties of the hybrid fiber reinforced RPC can be improved to some extent.
