Abstract

Abstract

In view of the insufficiency of durability of ordinary reinforced concrete structures in severe corrosive marine environments in South China Sea Islands, the basalt fiber reinforced polymer (BFRP) bar was proposed to reinforce coral reef and sea sand concrete. Axial compression test on 15 columns was conducted. The failure mode, load-displacement relationship and load-axial strain relationship were documented during the loading process. Test results indicate that, the failure of coral reef sand concrete initiates from the low strength coral reef aggregate, and finally experiences total failure at both aggregate and interface. The development law of column failure is characterized as three stages. The load capacity of BFRP coral reef and sea sand column is equivalent to that of steel bar.
