A Review on Self Cured Concrete

Abstract

The imagination of a world without concrete is impossible. Concrete is a soul of infrastructures. Concrete is necessary to gain strength in structures. Conventional concrete is a mixture of cement, fine aggregate, coarse aggregate and water needs curing to achieve strength. It is required to cure for a minimum duration of 28 days for good hydration & to achieve target mean strength. Lack of water curing can badly affect the strength & durability. Self curing concrete is one type of modern concrete, which cure itself by retaining water in it. For the same an admixture called Poly Ethylene Glycol (PEG) used as a self curing admixture. Many researchers used PEG by taking into account preparation & analysis of self curing concrete is done. Effect of admixture on compressive strength of M25 & M30 mix for 7, 14 & 28 days is analysed. This paper presents a review of all such authors who had used PEG in various forms for to determine its optimum doses and its various properties. Also its effect on the structures like permeability, porosity, corrosiveness and moisture content are checked.
