Abstract: Quality of concrete is calculated in terms of its 28days compressive strength. This period is too long for either control of concrete construction or applying timely corrective measures particularly in today’s fast construction practices. Curing of concrete and its gain of strength can be expedited by raising the temperature of curing, thereby speeding up of the hydration reaction. Two methods of accelerated curing – warm water method and boiling water method have been covered by IS 9013. The objective of this study is to compare 28 days compressive strength of concrete with accelerated curing methods developed by IS 9013: 2004. One more method of curing in which temperature was increased gradually was also attempted. In order to achieve these, total 48 samples of two different mix proportions were cast and cured by normal water curing for 28 days, and by accelerated curing methods. The reliability of these accelerated curing methods was checked
