摘要：
Recycled aggregate pervious concrete can alleviate the increasingly serious problems such as urban waterlogging, heat island effect and noise effect, but its basic performance, especially its strength is not high. In order to fill in the shortboard, the research of fiber modified recycled aggregate pervious concrete was carried out. According to the specification, on the basis of the standard mix ratio (water-binder ratio 0. 3, without fiber), three kinds of fibers including chopped basalt fibers, chopped carbon fibers and polypropylene fibers were designed and prepared which were included in 16 groups mix ratios. The compressive strength, splitting tensile strength, porosity and permeability coefficient were measured respectively. The results show that the compressive strength, splitting tensile strength and tension-compression ratio of recycled aggregate pervious concrete are effectively improved by adding fiber, and the modification of splitting tensile strength is better than that of compressive strength. Based on the method of Image, the effects of plane porosity, number of holes and average equivalent pore diameter of recycled aggregate pervious concrete on its strength and permeability are analyzed. At the same time, the Grey Theory and entropy method are used to comprehensively evaluate the fiber modified recycled aggregate pervious concrete. The results show that when the content of polypropylene fiber is 0. 3%, the comprehensive evaluation index is the highest, which is 84. 6%, and the comprehensive performance of recycled aggregate pervious concrete is the best. © 2022, The Editorial Board of Journal of Basic Science and Engineering.
