Properties of pervious concrete made with electric arc furnace slag and alkali-activated slag cement
Highlights The 28-d compressive strength of pervious concrete made with EAFS and AASC is 35MPa. Pervious concrete made with AASC has a lower BPN than that made with OPC. Pervious concrete made with AASC has low-frequency absorption for 125–250Hz.
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 35MPa while its permeability was higher than 0.49cm/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 0.24cm to 0.48cm) could reach 0.94 for low frequency noise (125Hz).
