To Study Sustainable Development of Concrete by Partial Replacement of Cement with Flyash and Alccofine

India is one of the fastest growing nations in the world. Many structures, mega structures are going in present time. All these structures are built with a very common and useful materialize Concrete. The approximate consumption of concrete of our world is one ton per person per year, and it's the second most consumed material after water. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600billioninre venue by 2025. The main objective of this work focuses on the compressive strength of concrete with partial replacement of cement with Fly ash and Alccofine. The project focuses on the experimental investigation on concrete by replacing cement with Fly ash and Alccofine on varying percentage. 25%, 50%, 75% and 100% for 7 and 28 days. The design mix carried out throughout the experiment will M25.
