EFFECTS OF SEAWATER AND SEA-SAND ON THE BEHAVIOUR OF FRP-CONFINED CONCRETE
This paper presents the results of a series of compression tests on FRP-confined concrete that was cast with seawater or sea-sand or both.A total of 48 standard concrete cylinders were tested in four series: reference normal concrete,sea-sand concrete,seawater concrete and seawater/sea-sand concrete.The concrete cylinders were either unconfined or confined with a 1-ply or 2-ply CFRP jacket.The unconfined specimens were tested at ages of 7 and 28 days and the confined specimens were tested at the age of 28 days.The test results show that concrete made with seawater and/or sea-sand developed a higher strength than normal concrete at the ages of 7 and 28 days.The test results also show that the four types of concrete have similar stress-strain behavior when confined with FRP; the use of seawater and sea-sand does not appear to have a significant effect on the effectiveness of FRP confinement.
