The construction industry today is one of the booming, employment and resource generating field in India. The increase in construction activities gives rise to vast demand for availability of materials used. But today due to the high construction activity the demand for river sand has increased to a greater pace as it being the primary material for the construction activity. The problem of sand mining is affecting the construction activity in our country. Excessive quarrying has caused the depletion of natural sand and causing flood problems. The government of India has therefore in some stated banned the use of natural sand. This ban has been affecting the construction process many a times the construction is stopped due to the unavailability of natural sand. The only option to this problem is the use of artificial sand or manufactured sand. The material is obtained by mechanically crushing the large rocks. The sand obtained is thus cheap, easily available and has shown better results as compared to the natural sand. The promotion of artificial sand will not only conserve the depleting natural resources but also give rise to speed and hassle free availability of material which will ultimately result in speed completion of work in given time and achieve economy in most of the aspect. The tests were conducted to show strength parameters of the concrete. It was found that compressive strength of the concrete increases with artificial sand. While in case of flexural strength the river sand holds good.
