FRACTURE MECHANICAL BEHAVIOR OF AGGREGATE-CEMENT MATRIX INTERFACES
Cracks in concrete tend to run along cement-aggregate interfaces. In fact, these interfaces serve as the weak links. In this paper, the adhesion between cement matrix and aggregate is quantitatively expressed by using the specific-fracture-energy concept. The specific fracture energy is obtained from the load-displacement curve of the wedge-splitting test. Smooth and dense limestone and porous, rough sandstone were used in the experiments to cover a broad range of aggregate materials. Based on the experiments, investigators conclude that specific fracture energy provides a useful tool for the fracture characterization of interfaces in cement composites.
