Abstract:

In the investigation, the applicability of linear-elastic fracture mechanics to portland cement pastes, mortars, and concretes was determined by the fabrication, testing, and analysis of plate specimens containing a precast flaw. A model was developed which provides a qualitative measure of the size of the microcracking zone which occurs in concrete. Experimental results are correlated with the model.
