Abstract: Introduction of new eco-friendly construction materials like steel slag is being necessary and promoted where exploration of natural aggregates for construction is restricted due to environment cause. Ecology gets threatened by disposal issue of steel industry waste products (Steel slag). This study focused on the properties of steel slag and its technical suitability in a concrete as replacement to coarse aggregates. Effects on workability, mechanical and durability properties were studied. Steel slag mixed concrete found suitable in mechanical properties, when in increase in percentage of replacement to coarse aggregates is high, whereas workability acted adversely. Optimum replacement (30 to 75 percentages) observed maximum results. Surface characteristics were affecting on workability and durability properties intensively. Steel slag aggregates found stable against acid attack, permeability, expansion, abrasion and temperature. This study culminates that the steel slag mixed concrete improves the properties of concrete than controlled concrete. Utilization of steel slag mixed concrete leads to sustainable and cost effective development.
