Abstract

In order to solve the problem of low strength and disintegrate easily using ordinary Portland cement-high sulfur tailings filling, we used blast furnace water quenching slag instead of Portland cement which was regarded as cement material to manufacture whole tailings paste for underground filling. We manufactured filling with blast furnace water quenching slag-high sulfur tailings and ordinary Portland cement on the base of analyzing the physicochemical property of whole tailings and blast furnace water quenching slag. Then we manufactured the standard test blocks to cure, and studied the strength of filling with different cement materials in accordance with uniaxial compressive test by the application of the machine of DYE-300 single shaft material test. Compared with cement filling, experimental results show that the strength of blast furnace water quenching slag, early stage or late stage, has a higher strength. And, moreover, it can solve the disintegrating problem caused by ordinary Portland cement-high sulfur tailings filling in the late stage.
