研究以煤矸石作为骨料制备混凝土的可靠性，将不同比例的煤矸石骨料替代普通碎石骨料制备煤矸石混凝土，进行了碱骨料反应、抗渗性能和抗冻性能试验分析。结果表明，试验选用煤矸石骨料均为非碱活性骨料；随着煤矸石骨料掺入量的增加，煤矸石混凝土抗压强度下降不明显，但其抗渗性能和抗冻性能则出现显著下降，自燃红矸石骨料掺入量宜控制在10%~20%，此条件下煤矸石作为骨料制备混凝土可行。

Aiming at studying the feasibility that coal gangues are taken as aggregates to prepare concrete, experiments on the aggregate reaction, permeability resistance and freeze resistance performance test analysis, which using different proportion of gangue aggregate replace ordinary gravel aggregate preparation of gangue concrete.The results showed that all coal gangue are non-active aggregate;within a certain range, coal gangue will not signiifcantly reduce the impermeability of concrete. With the increase of coal gangue, mechanical performance of coal gangue concrete has not been reduced, but frost resistance of concrete has been signiifcantly reduced in this paper. The red spontaneous combustion control between 10%~20%, under this condition it is feasible for coal gangues to be used to prepare concrete.
