Abstract

How to extend the service life of existing damaged (environmental corrosion) concrete structures has become a hot issue in the field of structural engineering. Using ultra-high performance concrete (UHPC) as the repair material of normal strength concrete (NSC), the interface bonding performance of UHPC-NSC has a significant effect on the overall force of the repaired component. In this paper, combined with the relevant experiments carried out by relevant scholars at home and abroad on the interface adhesion performance of UHPC-NSC, the effects of UHPC-NSC age, surface treatment of NSC matrix, moisture content of NSC matrix, strength of NSC matrix and UHPC curing method on the interfacial bonding strength of UHPC-NSC were analyzed. In addition, the dataset of UHPC-NSC interfacial shear strength under oblique shear test conditions was collected, and the interface bond strength of UHPC-NSC was predicted by artificial neural network (ANN) training, and the predicted value of oblique shear strength was in good agreement with the experimental value.
