This paper introduces the concrete of seawater and sea sand (SWSSC)
Used with fiber reinforced polymer (FRP)
And stainless steel to form a composite tubular section.
Industrial waste (slag)
Used to replace Portland cement production geography. polymer SWSSC.
Made of Grade 316 stainless steel, GFRP tubes are made through fiber winding process of various fiberglass orientation.
A series of tests were conducted on the SWSSC
Stainless steel and GFRP round tubes are filled under axial compression.
During the testing process, the core concrete and the outsourced pipe are loaded at the same time.
After reaching the peak load, concrete-
The stainless steel filler pipe can withstand the load stably.
It is found that the failure of the GFRP tube is the final failure mode of SWSSC-
Filled GFRP tube.
The test results show that the strength of the core SWSSC is greatly improved due to the restraint effect provided by stainless steel pipes and GFRP tubes.
Finally, the experimental limit carrying capacity of SWSSC-
Compare the fill tube to the predicted capacity.
