ACCELERATED TESTING FOR PREDICTION OF 28-DAY STRENGTH OF CONCRETE

There is a need for timely information on strength of concrete in construction works to help achieve better quality control. In India, not much work on accelerated strength testing of concrete has been reported, and there is a need for a systematic study of such testing by using locally available cements. This paper gives an account of an experimental study of accelerated testing of concrete for prediction of strength by using two methods based on suitable modifications of the British accelerated testing committee method and the Canadian modified boiling method. Concrete mixes with strengths ranging from 150 to 600 kgf/ sq cm (15 to 60 MPa) were tested. Test results, which were correlated by regression analyses, show that accelerated testing (hot-water curing for 3.5 hours at 85 C) can be used to accurately predict 28-day concrete strengths.
