Abstract

Curing of concrete is the process involved in maintaining satisfactory moisture content and maintain favourable temperature for hydration in concrete so as to develop the desired properties of concrete. However, perfect curing is not always possible in all cases. Self-curing concrete is the type of concrete that can cure itself with its retained moisture content. It is prepared with the addition of certain chemicals as self-curing agents. Earlier works conducted on self-curing concrete have indicated that these types of concretes have better strength, reduces rate of evaporation from surface, thermal properties, fire resistance, skid-resistance property improves, reduction in autogenous shrinkage, reduced chloride ion penetrability, improvement in freezing and thawing durability as well as the contact zone between aggregate and cement matrix and reduction in micro-cracking which results in better elastic compatibility compared to conventionally cured concretes. In this project work, the individual effect of curing agents like PEG 400, PEG 4000 & PEG 6000 on strength properties by varying the percentage by 0.5% and 1% were studied. The study shows that PEG 6000 with 0.5% could help in gaining maximum strength of curing. The test results showed that self-curing concrete is best option in places where water scarcity occurs.
