Abstract In this experiment, the effects of different steel fiber content (0%, 0.2%, 0.4%, 0.6%) on the compressive strength and permeability coefficient of pervious concrete were studied. Furthermore, the influence of aggregate size, fine aggregate and cellulose on the compressive strength and permeability coefficient of polyethylene fiber reinforced pervious concrete were researched. The results show that the polyethylene fiber can partly improve the early compressive strength of pervious concrete. With the increase of the content of the polyethylene fiber, the compressive strength of pervious concrete in 28 d increases first and then decreases, that is to say, there is an optimal content. The permeability of pervious concrete decreases first and then increases with the increase of the content of polyethylene fiber. The compressive strength of pervious concrete decreases with the increase of aggregate size, and the permeability coefficient increases significantly with the increase of aggregate size. Fine aggregate will reduce the 7 d compressive strength of pervious concrete, but will increase the 28 d compressive strength. With the increase of fine aggregate, the permeability coefficient of pervious concrete increases first and then decreases. The compressive strength of pervious concrete decreases with the increase of cellulose content, and the permeability coefficient increases with the increase of cellulose content. The research can provide a reference for the selection of admixtures in the practical construction process of pervious concrete.
