摘要
为了改善活性粉末混凝土的力学性能,采用了在活性粉末混凝土中混合掺加两种纤维的方法,即中等模量的耐碱玻璃纤维和低模量的聚丙烯纤维。本文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:两种纤维混杂后活性粉末混凝土的力学性能能够得到一定程度的改善。
Two kinds of fibers, which are alkali resistance glass fiber with medium elasticity modulus and polypropylene fiber with low elasticity modulus, have been added into the reactive powder concrete（RPC） for short in order to improve its mechanics properties. In this paper, study the impact of compressive strength and flexural strength of hybrid fiber reinforced RPC when the two kinds of fiber content changes. The results indicate that the effect of compressive strength and flexural strength can be improved to some extent.
