ABSTRACT
A plan of action is proposed to develop uses of non-ferrous slag and production of certain industrial materials from this waste material. A review of chemistry of non-ferrous slags suggested that it can be reprocessed to impart "cementitious" properties and furthermore an advantage could be taken of their latent "pozzolonaic" properties to test several potential applications such as - clinker ingredient, asphalt concrete additive, cemented mine backfill and binder for base stabilization. The development of construction materials have posed problems and challenge that initiated worldwide research programs and continued conventional and non conventional applications leading to ultimate economy. Researchers developed waste management strategies to apply for advantages for specific needs. Good quality aggregates are depleting and cost of material extraction is increasing, researchers are looking for suitable alternative materials. Industrial and domestic waste products provide a prospective source of alternative materials. These materials are cheaply available. Also, their use in road construction provides an efficient solution to the associated problems of pollution and disposal of these wastes.
Copper slag is one of the materials that is considered as a waste material which could have a promising future in construction industry as partial substitute of either cement or aggregates. Many researchers have already found it possible to use copper slag as a concrete aggregate. But not much research has been carried out concerning durability and corrosion studies of copper slag admixed concrete. This paper presents the results of an experimental study on various corrosion and durability tests on concrete containing copper slag as partial replacement of sand and cement. For this research work , M20 grade concrete was used and the tests were conducted for various proportions of copper slag replacement with sand of 0%, 30%, 40%, and 50%, in concrete. The obtained results were compared with those of control concrete made with ordinary Portland cement and sand.
