The most crucial component of concrete is Portland cement, which is also a versatile and rather expensive substance. Cement manufacture on a large scale affects the environment negatively and depletes natural resources negatively. Researchers are now using industrial waste materials as an additional cementing element in concrete because of the damage they pose to the environment. The M30 grade of varied water cement ratios of 0.32, 0.35, and 0.38 is used to create high-strength concrete. Instead of increasing the cement content, mineral admixtures (additional cementitious ingredients) are employed. In this study, M30 grade concrete with partial cement substitution by silica fume at levels of 5%, 10%, 15%, and 20%, with variable water cement ratios of 0.32, 0.35, and 0.38, is the key parameter under investigation. Compressive strength, flexural strength, and split tensile strength at ages of 7, 14, and 28 days are the subject of a thorough experimental research presented in this project. This article describes the findings of an experimental study on the impact of various silica fume (SF) and water to cement ratios (w/c) on standard concrete.
