Experimental study on replacement of fine aggregate in concrete with dissimilar curing conditions

The nation over, Scarcity of natural sand, water, and craftsmanship is at the zenith in the construction sectors. The construction industries are now inquiring other substitutes. This paper synthesized answers from the literature review and an experimental study carried out as per Indian Standards to 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 with SAP 0.3% & 0.4%]. The result shows that compressive and tensile strength properties were higher in self-curing with SAP 0.3% and air-shade curing shows the least value n both strength properties. (C) 2019 The Author.
