- Abstract
- The purpose of this study is to find the optimal concrete adhesion surface treatment about the construction joint when placing the UHPC. The adhesion surface treatments about the UHPC are a standard, a wire-brushing before harden, a resin adhesive, a silica fume mortar, a retardant+water-jet and the press and we accordingly implement the bonding shear performance evaluation. In conclusion, the interface preparation using a retardant and water-jet is a highest value of the specimens that the bonding shear strength is 42.1MPa. and the interface preparation using a silica fume mortar is a lowest value of the specimens that the bonding shear strength is 5.5MPa.
