The main objective of this paper is to study the effects of silica sand when used as a partial replacement to fine aggregate (natural sand). Natural sand in and around river bed plays an important ecological. The global consumption of natural sand has become very high due to excessive use of concrete. Hence the role, it acts as a giant aquifer and habitat for species. As a result of urbanization and increase in construction projects and activities, the available sources of natural sand is getting depleted. Demand for natural sand has become quite high and there is shortage of good quality natural sand. This research deals with the utilization of an alternative material, silica sand as partial replacement of natural sand. Silica sand is a by-product obtained as a result of cement manufactured by wet process. Silica sand acts as a filler material that is inert but enhances the process of hydration by physical activity. Due to the micro filling property of silica sand, the pores in concrete are reduced which improves moisture resistivity of concrete. Silica sand is replaced at 20%, 40%, 60%, 80% and 100% by weight of cement and the results are compared with the strength of conventional concrete. M25 grade concrete is taken for study. The optimum percentage arrived is 60% and it is to be noted that on 100% replacement the result obtained is on par with the results of conventional concrete.
