EVALUATION OF PHYSICO-CHEMICAL PROPERTIES AND DURABILITY ON SELF CURING CONCRETE BY USING PEG AND SAP

Concrete is the most imperative substantial of the building industry due to its durability and strength. As the present consumption of concrete in infrastructure and other construction industry is approximately 10 to 12 billion every year. The strength of concrete depends upon its constituent like the Cement, fine sand, coarse sand, fine aggregate & coarse aggregate. The cement is a calcareous material also known as binding material which reacts with water, gives strength and produces heat. Concrete gives their design strength when the proper curing is been done. Curing requires a large amount of water and the major portions of this water get evaporated due to heat hence more and more water is required for curing. If the curing is not done properly then it makes adverse effect on concrete. It is very challenging to do proper curing in water scare areas like desert areas, high rise building etc. This problem can be eliminated by the self-curing in place of conventional curing. Self-curing is done by the some admixtures like super Absorbent polymer and shrinkage reducing admixture. This research work is covers the use of Super Absorbent polymer and shrinkage reducing admixture in concrete for better hydration cementations material and gaining strength of concrete.
