Preparation method of pervious concrete with high steel slag content

The invention discloses a preparation method of pervious concrete with high steel slag content. The method comprises the steps: firstly, permeating steel slag with a water-based adhesive, then mixingcement with steel slag permeated by the water-based adhesive, finally adding water, and stirring to obtain the pervious concrete. The preparation method has the beneficial effects: (1) all aggregatesadopt the steel slag, so the resource utilization of the steel slag is achieved and the environmental pollution caused by the outdoor accumulation of the steel slag is reduced; (2) the steel slag is sprayed with the water-based adhesive firstly to make the water-based adhesive permeate to the interior of the steel slag through pores of the steel slag during preparation of concrete, and the compressive strength of steel slag particles after solidification is increased; (3) the compressive strength of the prepared concrete is high, the 28 d compressive strength reaches 29 MPa or more, and the water permeability coefficie
