A review is presented in this paper about the application of crushed sand as a smart material in concrete. After a brief outline of the theoretical as well practical studies few measures are reviewed to replace natural sand with manufactured crushed sand. This helps in reducing the likely damage to the ecological balance due excessive sand lifting from river beds, affecting the ground water level. Crushed sand as replaced materials to natural sand has become beneficial and is common in the world. Different researchers have carried out research to study the effect of use of crushed sand on properties of concrete. Hence, in this paper review of various operational parameters viz. workability, water absorption, compressive strength, flexural strength, tensile strength is highlighted.
