- In developing countries like India and China cement is being used in a large scale due its developmental activities. Hence they are the one of the largest cement produces in the world. Cement industries emit 10% of the world’s total carbon dioxide. So, India is also produces large amounts of CO2. Due to usage of large quantities of concrete we also consume huge amount of Natural River Sand leading to exploitation. Nowadays the government decision on sand mining ban has led to the scarcity of natural river sand. The solution to this problem is using the alternate materials like GGBFS and Copper Slag. The self-compacting concrete is a concrete, which has an ability to flow and consolidate under its own weight without need of any external vibration. In SCC flow property is achieved by chemical admixtures and stability and durability is achieved by filler material which reduced the bleeding in concrete. In this study is to determine the Mechanical properties of Self-Compacting Concrete by partially replacing GGBFS as cementatious material and Natural River Sand with Copper slag in different percentages (0%, 10%, 20%, 30%, 40%, and 50%) for M40 grade concrete. The examinations are done by embracing water powder proportion of 0.4, functionality tests, for example, droop stream, V-pipe, L-box tests are directed according to EFNARC rules at crisp state. Mechanical properties, for example, Compressive quality, split elasticity, flexural quality, Young's modulus tests was directed. It is indicated that ideal substitution level characteristic waterway sand by copper slag was seen as 40%.
