Abstract
Coal gangues, which are gotten from different six coal mines, were used as raw materials in the paper. The chemical compositions and the minerals of the original coal gangue have been tested. The results state that there is the different optimum temperature for the different coal gangue. For most coal gangues, the optimum activated temperature is 800. The 28days compressive strength of mortar with activated coal gangue can be increased when calcining coal gangue with a certain limestone. The structure of calcining coal gangue and calcining with limestone is tested by the method of NMR. The related mechanism of the calcining coal gangue is discussed in the paper.
