ANALYSIS OF GANGUE'S CHARACTERISTIC WHEN USING IT TO PRODUCE CONSTRUCTION MATERIAL

Gangue is a kind of discharge material in the process of excavating coal and picking coal.With the long time stacking,gangue may not only engross a great deal of land but also pollute the air and underground water and induce spontaneous combustion.Producing construction material by using gangue can save much soil and have very good benefit in the field of environment,society and economy.The demand on gangue's chemic component and technical capability in the process of making brick and producing cement is studied in this paper.Then,some guidance conclusions and experience prescription are presented.The conclusions have some reference meaning in solving the problem possibility brought in the production of construction material by using gangue.
