So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates. The concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions. This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and large construction projects where quantity of concrete consumption is huge..

· The second part of the program focused on the optimization of the selected design mix. The Natural River sand from Banas was mixed with crushed stone sand from Gunavata and Chandwaji and concrete design mixes corresponding to M25 and M30 grade of concrete were prepared. The samples were tested for slump, compressive strength and flexural strength.

Water table level get reduced due to dragging of the sand from the river and the roots of the tree may not be able to get water. In the absence of sand in river, water gets evaporated due to direct sun light. The slump is more. Water retentivity of mortar is more. Bulkage correction is required during mix design. Costly where river are far away.
