Effect of surface texture of precast ultra-high-performance concrete tubes on bond strength with normal concrete fill
This study investigated the bond behavior between prefabricated ultra-high-performance concrete (UHPC) tubes and normal-strength concrete (NSC) fill using push-out tests. Bubble-textured and corrugated interfac¬es were examined and compared with control specimens with a smooth interface. UHPC hoop reinforcement ratio ρ...
