Radiation shielding properties of concrete with electric arc furnace slag aggregates and steel shots

Highlights: ► Industrial waste products were used to produce radiation shielding concrete. ► The mechanical and radiation shielding properties were evaluated. ► The developed concrete is cheaper and conserves the natural resources. - Abstract: Heavyweight concrete, prepared with a mixture of concrete and heavyweight aggregates or metallic components, is generally used for radiation shielding purposes. In the present study the radiation shielding properties of concrete prepared with electric arc furnace slag aggregates (EAFSAs) and steel shots, was investigated. The results indicated that concrete mixed with 50% EAFSA and 50% steel shots meets the weight and radiation requirements. The use of 50% EAFSA results in a decrease in the cost of concrete and also conserves a useful material, such as iron ore
