Experimental Study on High Strength and high Flowable Concrete Filled Steel Tube for Practical Construction Application
합성강관 충전용 고강도-초유동 콘크리트의 현장적용을 위한 실험적 연구
Abstract
This paper presents a series of tests to produce the h~gh quality concrete to be filled Inside the steel tube columns. Thls concrete filled steel tube system requires not only the high strength, but a150 the flowable concrete. Laboratory test has been performed to clarlfy the material characteristics and to produce the optlmal mix design proportion. Full scale site mock up test has been then carried out to slnlulate the actual construct~on conditions including the product~on of concrete at the rermcon batch plant, transportation to the construction site, proper workabil~ ty and man power required , 4ddit1onal mock up test has finally been performec to irivesti gate any unfavorable construction s~tuatioils since the actual concrete placement has been sched uled in cold weather period, so that the high quality concrete construction is convinced to be successfully carried out.
