Abstract

Interlaminar shear behaviour has been investigated for basalt-, glass- and carbon fibre reinforced polymer (BFRP/GFRP/GFRP) bars in seawater and sea sand concrete (SWSSC), using an accelerated test. The investigation includes the influence of different short beam shear test methods and the effect of test span-to-diameter ratios on interlaminar shear strength. The degradation mechanism of FRP bars in SWSSC solutions has been characterised using moisture absorption and desorption tests, scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The long-term shear behaviour of BFRP/GFRP/CFRP bars in SWSSC environment has been predicted using Arrhenius theory.
