Abstract: | The paper presents the study on the relationship among mechanical properties, including compressive strength, splitting tensile strength, fracture toughness, and rupture probability of coarse aggregate (RPCA) of high-performance concrete (HPC) with varied aggregate sizes. For the maximum aggregate size of 16 mm, the compressive and splitting tensile strength and the corresponding RPCA reached the maximum values. As the mechanical properties linearly increased with the increasing RPCA, RPCA has been confirmed as a useful parameter to express the mechanical behavior of HPC. Preliminary analysis also showed good relationships between the mechanical properties and RPCA. |
