【摘要】 对杭联热电75t/h循环流化床锅炉燃烧内蒙古煤和淮南煤产生的脱硫灰成分进行了X射线衍射分析,进行了不同比例脱硫灰掺量条件下的混凝土配比实验,对混凝土的凝结时间、膨胀性以及抗压强度等物理性能进行分析。实验结果表明,CFB脱硫灰作为混凝土的掺合料,可以改善混凝土的性能,降低水泥的消耗,同时还可以降低成本和提高工程质量。更多还原

【Abstract】 A X ray diffraction analysis of desulfurization ash was given by burning Inner Mongolia coal and Huainan coal in the 75 t / h Circulating Fluidized Bed boiler( CFB) of Hangzhou Hanglian Thermal Power Co.,Ltd. The properties of concrete under the different proportions of desulfurization ash content were tested,which included the setting time,expansibility,and compressive strength. The results showed that CFB desulfurization ash,as a concrete admixture,can improve the performance of concrete,reduce the consumption of cement,but also can reduce costs and improve project quality.更多还原
