Experimental Study on Expansive Concrete Filled Steel Tube

Kai Cheng Huo, Xian Cheng Shu, Huan Yue

Abstract

Measure the temperature change of concrete-filled steel tubular with high strength low heat micro-expansive in its hardening process with different mix proportion. Study self-stress of high strength low-heat micro-expansive and study the relations of the expansive admixtures quantity and its changing regularity with the time. Observe the fail of axial compression short column of concrete-filled steel tubular with high strength expansive under vertical loading, study the changing regularity of its stress under loading.
