Fracture Energy of Concrete by Maturity Method

This paper has two objectives –1) to analytically develop and validate the hyperbolic relationship used in Yu et al.'s estimation of fracture energy and 2) to study the effect of curing temperature on the early and later age fracture energy development in concrete. The research involves extensive testing of cylinders, beams, and mortar cubes to determine datum temperature for both the mixture and the range of curing temperatures used in the experiments. Testing is conducted using the maturity method, a nondestructive testing technique that estimates the in-place compressive strength of concrete during construction by combining the effects of time and temperature into an index that correlates against in-place compressive strength. Results confirm the applicability of the hyperbolic relationship in terms of fracture energy gain, leading to the validation of the use of a nondestructive method for applications during concrete construction. The paper includes a brief explanation of the experiments, along with the analytical formulations used.
