Abstract – Curing is the name given to the procedures used for promoting the hydration of the cement, and consists of a control of temperature and of moisture movement from and into the concrete. Self-curing or internal curing is a technique that can be used to provide additional moisture in concrete for more effective hydration of cement and reduced self-desiccation. Self-curing distributes the extra curing water throughout the entire 3-D concrete microstructure so that it is more readily available to maintain saturation of the cement paste during hydration, avoiding self-desiccation and reduces autogenously shrinkage. The study investigates the effect of polyethylene glycol (PEG 400) on strength characteristics of self-curing concrete and the influence of poly ethylene glycol on mechanical properties are experimentally evaluating the Compressive strength, Splitting tensile strength and Flexural strength on the 7th and 28th days respectively.
