Abstract:A study of the method for prediction of potential strength of concrete based on the maturity concept is presented. The maturity which is expressed as the integral of the curing temperature with respect to time, is related to the compressive strength of standard cylinders cured at 33 oF (1.7 "C), 55 OF (12.8 "C), 73 OF (22.8 "C), and 90 OF (32.2 "C). The relationship between the compressive streng and maturity is obtained by regression analysis. Other published dat are also used in the analysis of the relationship. It is shown that the function relating the compressive strength to the logarithm of maturity is nonlinear and that the relationship is dependent on the strength-gain characteristics of cement and on water/cement ratio.
