Abstract: To explore the degradation mechanism of basalt fiber reinforced polymer (BFRP) reinforcement in the marine environment and evaluate the degradation degree of the corrosion resistance of coral concrete column with BFRP reinforced, the compression tests of BFRP bars, coral concrete and coral concrete column with BFRP reinforced were carried out in the marine environment. Based on the material tested results, the axially loaded tests were carried out on 12 coral concrete columns with BFRP bar reinforced. A micro test of scanning electron microscope (SEM) was put forward to measuring the internal BFRP reinforcement and coral concrete of failure members, and the chemical elements of basalt fiber and fiber-resin interface were tested and analyzed. The results showed that the ultimate bearing capacity of BFRP reinforcement was weakened more critically of dry and wet circulation conditions than that of soaking environment. The marine environment had little effect on the compressive performance of coral concrete. The bearing performance of axially loaded members greatly depended on the degree of corrosion and deterioration of internal reinforcement in failure specimens. Subsequently, based on the tested results, the change rules of different seawater corrosion categories and corrosion cycles on the internal BFRP reinforcement surface and the micro-component of coral concrete, and the influence mechanism of different factors on the durability of members were discussed and analyzed.
