Rapid urbanization has created a huge demand for non-conventional building materials by the construction industry. Sand is the major form of fine aggregate used in the preparation of concrete, however large scale depletion of river beds and increasing cost of sand have made the construction industry to go for other alternative form of fine aggregate. Many alternatives like different types of slags, industrial wastes, stone dust and agro wastes etc. have been tried to partially or fully replace river sand in preparation of concrete and the results have been encouraging. Copper slag is one of the alternative materials which has a promising future to be used as a fine aggregate in preparation of concrete. The preliminary strength studies conducted have shown that the optimum percentage of copper slag to be used as a partial replacement of sand in concrete is 40%. To prove any material as a building material it is highly imperative that along with the strength aspects of the material the durability aspects also verified. So as part of durability studies of copper slag concrete, an attempt has been made here to study the impact of acid attack on copper slag concrete and the results have been compared with that of normal concrete. M20 grade of concrete has been used for this experimental investigation. Test results shows that durability of the copper slag concrete found to be lower resistant to H2SO4 as compared to HCl and also controlled concrete has higher resistance to acid and sulphate attack as compared to copper slag concrete.
