摘要：
The scale effect on the cubic compressive strength of ultra-high performance concrete (UHPC) containing coarse aggregate with respect to the influences of coarse aggregate content and water-binder ratio was investigated via the uniaxial compressive tests. The results show that the coarse aggregate content has an influence on the scale effect of UHPC containing coarse aggregate. The scale effect degree of UHPC containing coarse aggregate is approximately 1.39 times as that of UHPC without coarse aggregate. The scale effect on cubic compressive strength of UHPC containing coarse aggregate decreases gradually with the increase of water-binder ratio. The scale conversion coefficient of cubic compressive strength of UHPC containing coarse aggregate was given. The parameter calculation formula of scale effect law was proposed, which could predict the cubic compressive strength of UHPC with coarse aggregate. © 2021, Editorial Department of Journal of the Chinese Ceramic Society.
