Abstract: Concrete, today is probably the most widely used construction material in the world. This is newlinenot only due to the wide range of applications that concrete offers, but also its great newlinestrength, affordability, durability, and versatility. The quality of concrete can be modified to newlinesuit specific requirements by using appropriate techniques. Curing, one such technique is newlineoften neglected in quality concrete production. The objective of curing is to protect newlinehardening of concrete till it reaches a certain degree of hydration so that desired long-term newlineproperties may develop. Conventional methods of curing include sprinkling of water over newlineconcrete surface and covering the concrete with wet straw and burlap, for which newlinerequirement of water is unavoidable. In hot arid zones, like Rajasthan, where the newlinetemperature varies to both extremes, and there is scarcity of water in most places, a direct newlineneed of alternative curing technique arises. It is imperative that curing technique can be newlineused in extreme climatic conditions, making use of available ambient energy without newlineutilizing any additional water except required for mixing the ingredients. newlineIt is well known that the amount of water in concrete while it is being placed is normally newlinemore than needed for curing. But, drying out of this water may not retain enough water for newlinehydration. Also, curing temperature of concrete is unarguably the variable that has the most newlinesignificant effect on rate of hydration. Further, if the freshly poured concrete is left exposed newlineto atmosphere, the relative humidity of concrete rapidly drops. The water evaporates into newlineatmosphere, and if the humidity level drops below 80 percent, the hydration reaction newlineactually stops affecting the characteristics compressive strength of concrete inversely. newlineTherefore, for exposed concrete, relative humidity and wind conditions are important; they newlinecontribute to the rate of moisture loss from the concrete and could result in cracking, poor surface quality and durability. The present study proposes use of impervious.
