Abstract :
Engineering properties of cement with coal gangue was studied to determine the compressive strength, freeze-thaw and shrinkage characteristics of the material. The composition of coal gangue was determined using the screening test; the liquid limit, plastic limit and water ratio of the cement with coal gangue were measured using the Liquid and Plastic Limit Joint Detector. The optimal water ratio of the cement with coal gangue was measured based on the water absorption rate of coal gangue and the cement water ratio. At the optimal water ratio the results indicated that the unconfined compressive strength, freeze-thaw characteristic and roadway contractibility can be improved by adding 10% cement into coal gangue.
