Abstract

This research aims to study the influence of interface joint types on shear bond strength between normal concrete (NC) and ultra-high performance concrete (UHPC) via a push-out test. Specimens with six different types of interface joints were tested. The results indicate that the shear bond strength between NC and UHPC varies significantly based on the interface conditions. Among the interface joints, groove joints showed higher shear bond strength than other interface conditions. These findings show the importance of interface design in optimizing the shear bond strength between NC and UHPC.
