Abstract

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%.
