摘要：

The technique of prestressing near-surface-mounted (NSM) carbon fiber-reinforced polymer (CFRP) has good potential and future prospects for structural strengthening due to its improvement of the bond between the CFRP and concrete. However, notably few investigations have been conducted to study the bond durability of the NSM CFRP-concrete interface. The present study was undertaken to increase the understanding of the durability of the bond between the NSM CFRP and concrete under freeze-thaw cycles. Pull-out tests were conducted to investigate ...
