Being cheapest in earlier days the natural sand used in concrete without any alternate even though natural sand
containing organic impurities, clay and silt content more than permitted level. Due to excessive mining the river basin
environment got affected, the demand for fine aggregate increased and the prevailing market unable to meet the need. Nowadays
crushed sand also called as manufactured sand being used as an alternate to natural sand partially or fully. an attempt has been
made to experimentally study the properties of concrete by replacing the 100% natural sand with artificial sand. The results
have shown that the natural sand can be replaced with the artificial sand to produce concrete of Satisfactory strength and
durability. Experiments conducted on M30, grade concrete with fine aggregate replacement proportion 10%,20% 30%,
40%,50%,60% and 70%. We have investigated workability, compressive strength for all different cases and cost analysis between
artificial sand and Natural Sand.
