- Abstract
- The joints in this construction are formed through the bonding shear evaluation method during the placement of ultra-high-performance concrete (UHPC). The evaluation items include push-off tests for homogeneous UHPC + UHPC. The experimental samples comprised a monolithic placement as the baseline, two levels for the separated placement according to the compression strength of concrete, and five levels for the interface treatment. The bonding shear performance for the homogeneous UHPC + UHPC construction linearly increased with the width and depth of the grooves used for the interface treatment. The increase in the number of grooves and their cross-sectional areas only slightly influenced the bonding shear performance. The optimal interface treatment method for the homogeneous UHPC + UHPC construction grooves was at least 30 mm.
