Experimental Investigation of Strength Properties of Self-Curing Concrete

Shravani Sachinkumar Sonavane*, S.K.Kulkarni


Concrete is most widely used construction material due to its good strength and durability. Conventional concrete, which is the mixture of cement, fine aggregate, coarse aggregate and water, needs congenial atmosphere by providing curing for a minimum period of 28 days for good hydration and to achieve desired strength. When there is water shortage, alternative curing methods become crucial. Different curing chemicals are employed in self-curing concrete (SCC) to cure concrete while preserving its moisture content. In the present study, Polyethylene Glycol (PEG) 400 is used as a curing agent. By changing the proportion of PEG by weight of cement to 0.75%, 1.25%, 1.75%, and 2.5%, its effects on compressive strength, split tensile strength, flexural strength, impact strength and pullout strength are investigated for M20 and M25 mixes. The study shows that PEG400 could help in gaining the strength of conventional curing. It is also found that 1.75% of PEG400 by weight of cement is optimum for M20 and M25 grade of concrete for achieving maximum strength without compromising workability. The test result indicates that the use of water-soluble polymer PEG400 for self-curing of concrete improves the performance of concrete. It traps the moisture within the structure and prevents it from evaporation which normally occurs during the hydration process.
