Quasi-Static and Dynamic Interfacial Bond Performance Between Ultra-Early-Strength Unsaturated Polyester Polymer Concrete and Ordinary Portland Concrete Under Flexural Loadings
Unsaturated polyester polymer concrete (UPPC) is a promising rapid repair material for pavement engineering, while the age-dependent and rate-dependent bonding behaviors between UPPC and ordinary Portland concrete (OPC) substrate remains poorly understood, restricting its application in heavy-traffic scenarios. This st...
