The nation over, the shortage of natural sand, water, and craftsmanship is going to the peak in the construction sectors. The construction industries are now finding out other substitutes. Here we compare the Strength properties of the concrete by natural sand, manufactured sand, and quarry dust with different curing methods for the conventional M20 grade concrete. The parameters of the research comprise the curing periods 7 and 28 days and curing methods Standard moist curing, Air-Shade curing, wet gunny bag curing, water sprinkling method, membrane wax-based curing, membrane resin-based curing, and self-curing. The compressive and tensile strength properties were found higher.

Mining on the river beds to encounter the increasing demand for sand from the construction industry has prompted serve natural disparity. The bigger issue is mining done under the guise of waterway bed. The natural sand available now is coarse and contains more amounts of clay, silt and other organic matters which affect the strength and durability of the concrete. In Tamil Nadu, India, scarcity of natural sand, water, and its volatile price escalation is a noteworthy reason for concern in the real estate and infrastructure sectors, especially in the major cities. Overcome this crisis; alternatives have come up for the industry to bank on of which manufactured sand or M-sand and quarry dust, both observed to be the most reasonable one to supplant river sand. Compared to the natural sand, the manufactured sand has a better superior consistency high Strength concrete with redeemable significance instrument. In concrete, Curing is the prime key factor for the life of the concrete structures. Curing guarantees additionally to maintain an adequate temperature of concrete in its first ages, as this directly influences the rate of hydration of cement and eventually the strength improvement of concrete or mortars. With improper curing, the hydration will not take place, and the resulting concrete may not get the expected strength and durability. The advancement in the chemical and construction sectors have led the way for development of new construction chemicals and techniques in curing of concrete such as Membrane curing compounds, self-curing agents, Water proofing compounds
