Abstract

This paper presents a development of seawater and sea sand concrete (SWSSC) which is used together with fibre reinforced polymer (FRP) and stainless steel to form composite tubular sections. Industry waste (slag) was used to replace Portland cement in making geo-polymer SWSSC. The 316 grade stainless steel was adopted and the GFRP tube was fabricated by the process of filament winding with various glass fiber orientations. A series of tests were conducted on SWSSC-filled stainless steel and GFRP circular tubes under axial compression. During the test, both the core concrete and encased tubes were loaded simultaneously. After reaching the peak load, concrete-filled stainless steel tubes could sustain the load steadily. GFRP tube rapture was found to be the final failure mode of SWSSC-filled GFRP tubes. The test results showed that the strength of the core SWSSC was greatly enhanced due to the confinement effect provided by the stainless steel tube and GFRP tubes. Finally, the experimental ultimate load carrying capacity of SWSSC-filled tubes are compared with predicted capacities.
