In the construction industry lot of natural sand is being used in the preparation of concrete. Levels of natural sand are depleting day by day. The cost of natural sand is also increasing every day. Therefore, there is a need for alternative materials to natural sand. In this study, exfoliated vermiculite is replacing natural sand partially. Vermiculite at 5%, 10%, and 15% is used for replacement. The concrete cubes are cast for M 30 grade to determine the optimal percentage of replacement of natural sand by vermiculite. In this study, coarse aggregate used includes both normal aggregate and recycled aggregate. The water-cement ratio of 0.45 is adopted. The durability tests conducted include the sulfate resistance Test and the chloride resistance test. The cost analysis was also done and results are presented. The test results are promising when vermiculite was used to replace natural sand at 10%.
