Abstract
Steel industry generate various kind of industrial waste, by-product after extracting final product as steel, depends on different types of ore refining methods. This research aims to identify experimentally, sustainable building material solution from waste to ingest in construction field centered on previous effort and literatures. EAF (Electric arc furnace) slag, a kind ofwaste material has an excellent potential to replace the natural coarse aggregate in concrete. The evaluation of the physical, chemical & microstructure properties of EAF slag as aggregate shows reasonably enhanced results. The M-50 grade of concrete was designed with various EAF slag replaced (0, 25, 50, 72, 100%) in place of natural coarse aggregate. It is observed thatfresh and hardened concretewith 50% EAF slag replacement exhibits outstanding performance over conventional concrete.
