Abstract: Artificial sand also called manufactured sand or crushed sand, the prepared by crushing rocks, stones or larger aggregates into small size particles in the quarry. Recent years, with the decrease of natural sand, the market of artificial sand shows great potential and vitality. The huge demand of the construction market has encouraged the development of the artificial sand market rapidly. Natural sand is worn out particles of rocks and are of various grades or sizes depending upon the amount of wearing. At present good sand is not readily available, it is transported from a long distance. Those resources are also exhausting very rapidly. So, it is a need of the time to find some substitute to natural sand. The Artificial sand produced by proper machines can be a better substitute to natural sand. Well graded sand is expected in the concrete. When fine particles are in proper proportion, the sand will have fewer voids. The cement quantity required will be less. Such sand will be more economical. Demand for manufactured sand for making concrete is increasing day by day as natural sand cannot meet the increasing demand of construction area. Natural sand takes number of years to form and is not replenishable. Because of its inadequate supply, the cost of Natural sand has increased and its steady supply cannot be assured. Under these situations use of Artificial sand becomes unavoidable. Natural sand in many parts of the country is not graded properly and has excessive silt and organic impurities and these can be harmful to durability of concrete whereas Artificial sand has no silt or organic impurities. In the present paper an attempt has been made to experimentally study the compressive strength of concrete cubes prepared with natural and artificial sand.
