This experimental work was carried out to investigate the effect of concrete strength in terms of compressive and split tensile strength of normal strength M20and medium strength M40 grade concrete by adopting Immersion curing, Wet gunny bags curing and Accelerated warm water curing as per 10262: 1999, IS 9031: 1978. Traditionally, quality of concrete in construction works is calculated in terms of its 28 days compressive strength. If after 28 days, the quality of concrete is found to be dubious, it would have considerably hardened by that time and also might have been buried by subsequent construction. What is essentially needed for assessing quality of controlled concrete is an acceptance test which can supply results, within about 24 hours after casting. With the assistance of reliable test methods employing accelerated curing techniques, it is now possible to test the compressive strength of concrete within a short period and thereby the test results of compressive strength and split tensile strength having good agreement with the specified strength at 28 days.
