The Experiment Research of a New Cementing Material Applied in Iron Tailing Filling

Abstract:

Previous studies found that there were some problems when processing goaf by filling method, such as large amount of cement, and high cost. A new type of cementing material was investigated in this study. Its main ingredients was graining blast furnace slag. on the chemical activation, its activities were substantially improved, and the technical parameters of the filling body were markedly ameliorated. Furthermore, the new cementing material complied with the filling cementing material standard of China. The results demonstrated that the new type of cementing material which overcome some traditional shortconmings could be the pottential material for the similar mines which exploit ores by back-filling method.
