Abstract: One of the constituent of concrete is natural sand or river sand. The issues of environmental degradation and expensive nature of the river sand are increasing day by day. The Global consumption of natural sand or river sand has become more due to excessive use of concrete so that the demand of river sand is very high and there is shortage of good quality of river sand. These reasons make us to switch on the alternative sources. Many researches has been done yet to replace the river sand. The objective of this research is to an experimental study of concrete using eco sand as a replacement of fine aggregates. So Eco Sand is replaced with 5%, 10%, 15% and 20% by weight of fine aggregates and mechanical properties such as Compressive strength, Spilt Tensile strength and Flexural strength are investigated. Eco sand acts like filler minerals which helps to reduce pores, reduce moisture resistivity. M40 grade of concrete is taken for study. The rheology studies are also made in detail as the fine content of concrete increases, the water demand increases to make it workable. Hence to overcome this problem, 1% of chemical admixture (water reducer) i.e., super plasticizer is used. The compressive strength, flexural strength and split tensile strength increase when fine aggregate was replaced by eco sand at 5, 10, 15, and 20%. The Optimum percentage of replacement is 15%.
