· 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.

 · Moreover desert sand is monograined, meaning of similar size. This makes it unsuitable for use in concrete, which requires small, intermediate, and coarser particles to prevent voids between grains and reduce the amount of water necessary. Instead, then, sand for construction has traditionally been mined from land quarries and riverbeds.
