In this study, stresses and strains of mortar and coarse aggregate in high strength concrete under compressive stress condition were estimated based on stress-strain curves of concrete, mortar, and coarse aggregate, and the destruction mechanism of high strength concrete was examined. The results indicated that the destruction of high strength concrete is caused in the stress of mortar becoming near its compressive strength when compressive strength of coarse aggregate is higher more enough than that of mortar, and that the average strain of mortar when concrete made using coarse aggregate with high Young's modulus is destroyed is small.
