The paper presents a method of predicting the standard 28-day concrete strength using the accelerated strength test results. Based on the concept of maturity, a relationship is developed between the 28-day and accelerated strengths using time and curing temperature as variables. A regression equation is obtained by using results of these investigations. The application of the relationship is evaluated for a different set of experimental results not used for the regression. It is concluded that the maturity concept can be used with acceptable accuracy to predict the standard 28-day strength. (TRRL)
