【摘要】 本研究旨在探讨燃煤炉渣微粉作为混凝土掺合料的可行性。以内蒙古某火力发电厂的燃煤炉渣为研究对象，将其作为混凝土掺合料，测试不同燃煤炉渣微粉掺合率下混凝土的力学性能和孔结构。结果表明，燃煤炉渣微粉混凝土的抗压强度随掺合率增加而降低，但10%掺合率时超过普通混凝土；适量燃煤炉渣微粉能改善混凝土孔结构。因此，燃煤炉渣微粉可作混凝土掺合料，尤其在低掺合率下能显著提升混凝土性能。更多还原

【Abstract】 This study aims to investigate the feasibility of coal-fired slag powder as a concrete admixture. Taking the slag of coal coal in Inner Mongolia as concrete admixture, the mechanical properties and hole structure of concrete at different coal slag mixing rate are tested. The results show that the compressive strength of coal slag concrete decreases with the mixing rate, but the 10% mixing rate exceeds the ordinary concrete; the appropriate amount of coal slag powder can improve the concrete hole structure. Therefore, coal burning slag powder can be used as concrete admixture, especially at low mixing rate can significantly improve the concrete performance.更多还原
