Indian Concrete Journal - ICJSummary: In order to bring sustainability in construction, nowadays, many industrial solid wastes are used as a partial replacement for cement as well as aggregates. Using industrial wastes in construction solves dual problem of waste disposal and depletion of natural resources. Steel aggregate is one such industrial solid waste having potential to replace the conventional river sand. In this study, an attempt has been made to investigate the performance of steel slag aggregates in concrete as a partial replacement for conventional river sand. Three mixes were made for this study, first mix made of ordinary Portland cement (OPC) and 100 % river sand (0M0), second mix (0M50) made of OPC and 50 % river sand replaced by slag aggregates and third mix (25M50) made of 25 % fly ash and 75 % OPC, and 50 % slag aggregates. Tests for assessing the mechanical and durability properties were conducted. The results showed that the strength and durability of concrete made with steel slag aggregate and river sand were comparable. This study shows the suitability of using 50% steel slag aggregates as a partial replacement for river sand in concrete.
