Concrete is a building medium usually referred to as composite concrete made up of various materials such as cement, fine aggregate, coarse aggregate, etc. Infrastructural requirements have brought the domestic and construction industries great momentum at an immense pace. Many civil engineers have been restricted by the incessant use of concrete to add some related constituents in proportion to the cement or some other element in order to have some influence over the depleting cycle of concrete usage from the universe. In addition, the leaps and bounds of non-biodegradable waste are rendering significant problem on flora and fauna so its control and disposal is now a great concern for the biodiversity. In our tests, the weight fraction of cement is incorporated into the concrete grades M20, M25 and M30 by 2 percent, 3 percent, 4 percent and 5 percent. Contrasted with conventional concrete, concrete compressive strength was evaluated and a trend was discovered which was tested in compliance with the principles of civil engineering.
