硫酸盐与氯盐环境下大掺量煤矸石混凝土性能

Mass coal gangue concrete performance under the sulfate and chloride salt environment

采用硫酸盐侵蚀和NEL法,对大掺量煤矸石混凝土经过硫酸盐侵蚀后的质量损失、强度损失等进行了试验研究,并分析了煤矸石混凝土抗压强度与碎石掺量之间的关系,得出了一些有意义的结论,对预测、控制和改善大掺量煤矸石混凝土的性能具有一定的实际意义。

Using the sulfate erosion and NEL method,this paper made test research on weight loss,strength loss etc. of mass coal gangue con-crete after sulfate corrosion,and analyzed the relationship between coal gangue concrete,compression strength and gravel contents,drew some meaningful conclusions,had certain practical significance to predict,control and improve the performance the mass gangue concrete contents.
