Abstract

This paper presents a series of tests to produce the high quality concrete to be filled inside the steel tube columns. This concrete filled steel tube system requires not only the high strength, but also the high flowable concrete. Laboratory test has been performed to clarify the material characteristics and to produce the optimal mix design proportion. Full-scale site mock-up test has been then carried out to simulate the actual construction conditions including the production of concrete at the remicon batch plant, transportation to the construction site, proper workability and man-power required.
