Interface behaviour of carbon-fabric-reinforced cementitious matrix composites with ICCP technique Available to Purchase

This paper studies the interface bonding performance of carbon-fabric-reinforced cementitious matrix (C-FRCM) composites with the impressed current cathodic protection (ICCP) technique. Single shear tests and pull-out tests on the C-FRCM composites are launched. Three current densities of 0, 100 and 150 mA/m² in the ICCP technique are considered. The resistance–slip relationships for all the composites are presented. It is found that the maximum resistance of the specimens in the pull-out tests decreases significantly with the increase of current density in the ICCP technique. Moreover, numerical analyses are conducted to obtain a simplified interface bonding stress–slip relationship of the specimens in the pull-out tests.
