Abstract – Global construction organization use a lot
of materials like cement, sand, and aggregate etc. In previous years it is very important to lesser the price of construction materials. Day by day the price of cement and sand are at peak so that countries rich and influence people can afford construction. The development of new era and using low budget materials that can be replace cement and sand by fully or partially in civil work. Cement and sand plays a major role in construction field. Thus, cement is massively expensive due to transportation from required locations. Due to large production of cement the global warming is harmed at higher rate in atmosphere by carbon dioxide. To save the environment and reduce the price by alternative materials such as silica fume and marble dust an innovative idea for such further generation by partially replacing cement by silica fume and river sand by marble dust. Since the replacement Silica fume is used to replace cement in percentages of 6%, 12 percent, 18 percent. Sand is replaced by marble dust in percentages of 8%, 18%, 28%, respectively. This experiment is carried out by flexural and compressive strength test are obtained.
2.1.CEMENT: As per IS 8112:1989 oridnary Portland cement 53 grade (OPC-53). Cement used was of ACC cement. The properties of cement are given table below.

2.3.FINE AGGREGATE:
All the materials used in many construction fields is mostly concrete. For any kind of construction works such as tunnels, bridges, high rise buildings etc. Concrete is required. As the importance of concrete for construction the replacement should be at similar alternative. Each and every material has its own importance for overall performance of construction. Such ingredients like cement, sand, aggregates etc are required for concrete. As the natural materials are consumed at higher rate CO2 are produced at peak in atmosphere. The river sand is also plays every crucial role in concrete strength such as cement. So the cement and river sand are replaced by silica fume and marble dust artificially produced materials are partially replaced and this study performance are carried out on M25 concrete.
