Abstract

Industries are one of the major source for the generation of wastes. Of all the industries, metallurgical industries generate tonnes of wastes in the form of sludges and slags. In this review article, a detailed study is made on the various types of slags that are widely generated and its characteristics properties. Study is made on secondary lead slag, copper slag, iron and steel slag. The physical, mechanical and chemical properties of these slags are studied and compiled. The obtained values are compared with the requirement standards given by various institutions. The study reveals that most of these slags can be effectively used as pavement material, ballast stones, partial replacement or alternative to coarse & fine aggregate and as fill material. Utilization of these slags in bulk quantity is highly recommended as they reduce the consumption of the conventional natural material. Moreover, disposal of such industrial wastes are costly in terms of money and space as well. However, the leaching potential of the slags has to be verified before application.
