Concrete is the most widely used construction material in any structure. To meet the requirement of globalization, in the construction of buildings and other structures, concrete plays a major rightful role and an increase in construction activities has led to utilizing the quality of concrete and also an increase in demand for various raw materials in concrete. Concrete is a combination of cement, fine aggregate, coarse aggregates and water. Natural sand deposits are being depleted and causing a serious threat to the environment as well as society. If the usage of sand increases continuously then after some years, we will face serious problems with respective its availability, cost and environmental impact. Recently the government of Andhra Pradesh and Tamil N?du has imposed restrictions on sand removal from the river beds due to unsafe impacts threatening the states. To overcome these problems, there is a need for cost-effective; alternative and innovative materials nowadays sustainable infrastructural growth demands alternative materials that should satisfy the technical requirements of the fine aggregate. Mix design is designed as per IS Standards. In this research, a mix of 1:1.9:3.1 (M20) was considered. The test specimen was cast for 7 days, 14 days and 28 days. The performance of M-sand was determined by several experiments such as slump test, split tensile strength, flexural Strength, and compressive strength test. The results attained from each test state that as M-sand increases the slump value decreases. flexural strength, compressive strength and split tensile strength of concrete at 7 days, 14 days and 28 days are greater at 60% replacement of M sand by river sand.
