Abstract
In this paper correlation in compressive strength of concrete using accelerated curing and normal 28days curing has been discussed. The work has been carried out especially on M45grade and M40 Grade concrete pump able mix. After finalisation of mix design cubes were casted for each grade as per Indian standard. The cubes were tested by accelerated curing test method specified in IS 9013:1978 and 28days compressive strength as per IS516:1959. These compressive strength results were analysed It was observed that compressive strength of cubes after 28days curing and that of after accelerated curing have a variation ranges from 2% to 7%.approxmately.Therefore it was concluded that under controlled test condition strength determined by accelerated curing test is always higher than normal 28days strength.
