Due to exponential growth in the usage of concrete world over, there is a huge demand for natural river sand as construction material. Off late, this excessive consumption of sand led to acute shortage and led to slowing down of construction projects. Hence to protect the natural shore line, a necessity is felt to find suitable replacement material for sand in concrete as concrete is consumed second largest in the world. In this work copper slag which is an industrial waste is used as a replacement material for sand and its effect is studied on the strength of concrete. Also, to improve the strength and ductility, polypropylene fibers are added in the ratios of 0.1%, 0.2%, 0.3% and 0.4% content. The effect of copper slag is investigated by replacing fine aggregate in concrete in the proportions of 10%, 20%, 30%, 40%, 50% 60% and 100%. The results obtained are analyzed and presented. |
