Concrete is mostly used construction material due to its good compressive strength and durability. Depending upon the nature of the work cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for a good hydration and to attain desire strength. The properties of hardened concrete, especially the durability are greatly influenced by curing since

Self-curing concrete is one of the special concrete in mitigating insufficient curing due to human negligence, paucity of water areas, inaccessibility of structure in difficult terrains and in areas where the presence of fluorides in water will badly affect the characteristics of concrete. The present study involves the addition of polyethylene glycol (PEG-400, with weight of cement in different ratios) in concrete and compared with that of conventional cured concrete.
