Abstract

Conventional concrete exhibits a size effect in compressive strength testing, whereas ultra-high-performance concrete (UHPC) shares a closer composition with ordinary mortar. This study investigates the compressive strength of cubic specimens with dimensions of 70.7 mm × 70.7 mm × 70.7 mm and 100 mm × 100 mm × 100 mm, analyzing their strength at different curing ages and deriving a 28-day strength ratio coefficient. The findings provide detailed performance data for UHPC, supporting both engineering applications and experimental research.
