Abstract: Abstract: In this paper, the properties of pervious concrete made with electric arc furnace slag (EAFS) and alkali-activated slag cement (AASC) were investigated. It was found that the mechanical strengths of pervious concrete made with AASC were higher than those of pervious concrete made with Portland cement. The 28-day compressive strength for pervious concrete made with EAFS and AASC exceeded 35 MPa while its permeability was higher than 0.49 cm/s. The British pendulum number (BPN) for the pervious concrete made with AASC was lower than that made with Portland cement, which implied the pervious concrete made with AASC had a better anti-skid performance. In addition, the sound absorption ratio for the pervious concrete made with EAFS and AASC (void filled percentage of 90%, and aggregate size in the range from 0.24 cm to 0.48 cm) could reach 0.94 for low frequency noise (125 Hz).
