聚丙烯纤维高强混凝土的配制及基本力学性能试验研究

Experimental study on the preparation of polypropylene fiber reinforced high-strength concrete and basic mechanical performance

本文选用合适的地方材料,采用正交试验设计法得出C60高强混凝土的最优配合比。在高强混凝土中掺加不同掺量的聚丙烯纤维,进行混凝土立方体抗压强度、劈裂抗拉强度和抗折强度试验。试验发现:聚丙烯纤维对混凝土抗压强度几乎没有影响,劈裂抗拉强度和抗折强度则有显著的提高。

In this paper, appropriate local mixture ratio design is obtained materials is selected and the optimal C60 high-strength concrete through the orthogonal experimental design method.By c polypropylene fiber content in high-strength concrete,the strength ,split tensile strength and folding strength.The study hanging the paper researches on concrete cube compressive shows that the polypropylene fiber has little ira- pact on concrete pressive strength, but split tensile strength and folding strength of C60 high-strength concrete are significantly improved.
