Properties of pervious concrete made with air-cooling electric arc furnace slag as aggregates

Abstract

In this paper, properties of pervious concrete made with air-cooling electric arc furnace slag (EAFS) as aggregates are investigated. Test results showed that under the same condition, pervious concrete made with EAFS aggregates had a better mechanical strength and a greater permeability coefficient than that made with natural river gravels. In addition, pervious concrete made with EAFS aggregates had a lower weight loss than that made with natural river gravels for the soundness tests. The dimension stability test showed that the possible expansion characteristic of EAFS became not so significant for pervious concrete due to the voids inside the system. It is concluded that pervious concrete made with EAFS aggregates is a good alternative in many ways. (C) 2015 Elsevier Ltd. All rights reserved.
