Slag and coal gangue are used as supplementary cementing materials in the blend cement, and the effect of the fineness and the blend ratio of slag and coal gangue on the strength of the blend cement is studied. With the strength of the cement mortar as the parameter, the best composite system is identified. It is shown that for the composite system consisting of slag and natural gangue, the slag fineness determines the strength of the composite cement, the finer the slag, the higher the strength of the blend cement. With a given total amount of slag and natural coal gangue as the mixed material to replace the cement aggregates, the composite cement strength increases with the increase of the slag proportion and with the decrease of the gangue proportion. The natural coal gangue is not active, and the activity is only shown after calcination.
