The experimental investigation involves study of physical, chemical and micro-structural characterization of mill scale. This provides the step one for its feasibility study in concrete industry. Before getting into the experimental results, a brief overview of the current research scenario is presented in the forthcoming section.
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic

steel mill scale, which is produced as a waste material in steel industries. A detailed experimental study was carried out to determine the effect of replacement of fine aggregates in high strength concrete with steel waste. Three grades of fine aggregates and steel waste were used for attaining optimum packing density.
Apr 24, 2018 Copper slag is a hard, dense abrasive with angular particles is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Blasting the copper slag grit at the surface is reported to be a very effective for metal surface cleaning before paint spraying.
