【摘要】:以页岩煤矸石等质量取代天然石子作为粗骨料制备煤矸石混凝土,测试了煤矸石混凝土的工作性能及力学性能,研究了页岩煤矸石混凝土抗冻性、电通量及干燥收缩等耐久性因素。结果表明:随着页岩煤矸石掺量的增加,混凝土的工作性能逐渐略有降低,抗压强度逐渐增大;混凝土耐久性略有降低,但能满足要求;页岩煤矸石作为混凝土粗骨料制备混凝土切实可行。
[Abstract]:Coal gangue concrete was prepared by replacing natural stone with shale gangue as coarse aggregate. The working and mechanical properties of coal gangue concrete were tested, and the frost resistance of shale gangue concrete was studied. Electrical flux and drying shrinkage and other durability factors. The results show that with the increase of shale gangue content, the performance of concrete decreases slightly, the compressive strength increases, the durability of concrete decreases slightly, but it can meet the requirements. It is feasible to use shale gangue as coarse aggregate of concrete to prepare concrete.
