【摘要】：以煤矸石粗细骨料为研究对象,通过理论分析与试验研究,对不同热活化活性与原状煤矸石进行研究,分析了煤矸石集料取代率、水灰比等对混凝土的力学性能的影响,为煤矸石作为混凝土集料的选用原则提供科学的理论基础,对推广煤矸石集料混凝土的实际应用有着重要的意义。
[Abstract]:Taking the coarse and fine aggregate of coal gangue as the research object, through theoretical analysis and experimental study, the different thermal activation activity and the original coal gangue are studied, and the influence of coal gangue aggregate substitution rate and water-cement ratio on the mechanical properties of concrete is analyzed. It is of great significance to popularize the practical application of coal gangue aggregate concrete by providing a scientific theoretical basis for the selection principle of coal gangue as concrete aggregate.
