Abstract：Single particle size recycled brick coarse aggregate,cement,water and proper amount of polypropylene steel fiber (PPTF) were used to prepare new water-permeable concrete. The influence of the amount of polypropylene steel fiber,the target porosity and the ratio of water to cement on the mechanical properties and water permeability of the concrete was researched. When the water-cement ratio is 0.30~0.34,the target porosity is 22%~26%,the polypropylene steel fiber content is 3~4 kg/m3,the polypropylene steel fiber crack enhancement effect is most obvious,the water permeability is reasonable and the strength is higher.
