Abstract

An experimental study was conducted to investigate the axial compressive performance of CFRP-confined concrete after exposure to a cyclic wet-dry environment with 3.5% salt solution. A total of sixty 150x300mm concrete cylinders unconfined or confined with CFRP were tested. The test parameters included the number of wet-dry cycles (0, 60, 120, 240 and 360) and the number of CFRP layers (0, 1, 2 and 3). The results show that the axial compressive strength and hoop strain of concrete confined with three layers of CFRP were reduced by up to 13% and 19% respectively after 360 wet-dry cycles. The ultimate axial strain increased with the increase of the number of CFRP layers, but the effect of the number of wet-dry cycles was insignificant.
