摘 要:研究了煤矸石分别等体积替代粗骨料、细骨料(0、5%、10%、15%、20%、25%)对混凝土工作性、干表观密度和力学性能的影响。结果表明:掺入煤矸石粗骨料或细骨料总体上会导致混凝土的工作性、干表观密度和力学性能下降;综合考虑,推荐煤矸石粗骨料或细骨料的掺量均为5%。
Abstract: The effects of gangue replacing coarse and fine aggregates (0, 5%, 10%, 15%, 20%, 25%) in equal volume on the workability, dry apparent density and mechanical properties of concrete were studied. The results show that the addition of gangue coarse or fine aggregates generally leads to a decrease in workability, dry apparent density and mechanical properties of concrete. The recommended content of gangue coarse aggregate or fine aggregate is 5%.
