Self-Curing of Concrete Incorporated with Polyethylene Glycol
Abstract: Concrete is a combined mixture of cement, aggregates and water with or without suitable admixtures. Curing is the process of sustaining the proper moisture content to stimulate optimum cement hydration immediately after placement and to achieve desirable strength and other properties. In conventional curing of concrete, this is achieved by external supply of water after mixing, placing and finishing of concrete. In practice, the conventional type of curing is very …
