摘要

摘要: 通过制备8种不同纤维掺量的聚丙烯纤维再生砖混凝土（PFRB混凝土）进行单因素试验，分析纤维掺量对其力学性能（立方体抗压强度、轴心抗压强度和劈裂抗拉强度）的影响，得到了立方体抗压强度和轴心抗压强度、立方体抗压强度和劈裂抗拉强度之间的关系式，并建立了不同纤维掺量下PFRB混凝土受压应力-应变全曲线方程。试验发现：随着纤维掺量增大，PFRB混凝土的轴心抗压强度、立方体抗压强度和劈裂抗拉强度均先增加后降低，并且都在纤维掺量为0.1%时达到最大。

Abstract: Eight kinds of recycled brick concrete(PFRB concrete)with polypropylene fibers were designed, in which the fiber content was different. The mechanical tests were conducted. The influence of the fiber content on the mechanical properties (cube compressive strength, axial compressive strength and splitting tensile strength) was analyzed based on the test data. Relational mathematical expressions between cubic compressive strength and axial compressive strength, and cubic compressive strength and splitting tensile strength were obtained. And the compressive stress-strain curve equation of PFRB concrete were constructed. The research result showed that with the increase of the fiber content, cubic compressive strength, axial compressive strength and splitting tensile strength of PFRB concrete first increased and then decreased, and the peak strength was in fiber content of 0.1%.
