An Experimental Investigation of Effect of Variation of Curing Condition on Compressive Strength of Self Compacting Concrete

In this paper, we investigate the effect of curing condition on the self-compacting concrete with age and duration of lapses in curing of concrete. In this fast developing world where time is most precision, Builders and contractors cannot engage their valuable precision in 28 days in curing of each and every element of the structure unknowingly or under unavoidable circumstances. It may possible that curing could not be done continuously i.e. breaking of curing process; this is general problem for high rise structure where it resists speedy construction. Lack of scaffolding can also create a problem. This work is mainly concerned with mix design of self-compacting concrete of grade M25 and studies the variation of curing time on concrete compressive strength. These cubes for mix design of M25 self-compacting concrete were cast using OPC 43 grade cement concrete and were cured for 28 days with breaking of curing process for 1st day, 2nd day. In 84 numbers of cubes and also sample sets were cured continuously 7 days 14 days 21 days and 28 days and was tested for characteristics strength of concrete due to breaking of curing process within 1st 10days of curing, after10days continuous curing, breaking of curing process effects in the compressive strength of cement of concrete after 28 days. The concrete cubes gain strength about 31.6n/mm2 of the target compressive strength for OPC of cured for first 7, 14, 21, and 28 days respectively.
