        abstract = {For a considerable amount of time to come, concrete will continue to be the most adaptable material utilized in construction. The mixture of cement, fine aggregate, coarse aggregate, and water that is known as conventional concrete it requires curing to obtain the appropriate strength. In order for the concrete to acquire the necessary rheological qualities for mixing, transporting, putting, and compacting, water must be added during the mixing process. One of the major considerations achieving the required properties is gaining control on water curing is the process of encouraging the cement to hydrate it involves regulating the temperature as well as the flow of moisture into and out of concrete.one of the most important aspects in curing is the need to maintain relative humidity of around 100% otherwise the improper curing causes shrinkage and crack in the concrete. Curing is mainly performed by water adding techniques and water retaining techniques. In internal curing hydration of cement occurs due to the availability of water not adding additional water. The function of Internal-curing agent is to reduce the water evaporation from concrete, and hence they increase the water retention capacity of concrete compared to the conventionally cured concrete.
In the present study, Polyethylene glycol-400 used as the internal curing agent. The effect of adding admixture (PEG 400) on compressive strength, split tensile strength and modulus of rupture by varying the percentage of PEG by weight of cement from 0% to 2.5% were studied for M25. It was found that PEG 400 could help in Internal-curing by giving strength on par with conventional curing.
