摘要

研究了煤矸石水泥的工程性能，确定了材料的抗压强度、冻融特性和收缩特性。通过筛选试验确定了煤矸石的组成;采用液塑结合部测定仪测定了煤矸石水泥的液限、塑限和水比。根据煤矸石吸水率和水泥含水率，确定了煤矸石水泥的最佳含水率。结果表明，在最佳含水率下，煤矸石中掺入10%的水泥可改善无侧限抗压强度、冻融特性和巷道收缩性。

Engineering properties of cement with coal gangue

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.
