【摘要】 稻壳灰是稻壳燃烧后产生的灰分,在一定的燃烧制度下,稻壳灰能获得可供进一步应用的优良性能。用低碳稻壳灰作胶凝材料代替部分水泥,是利用稻壳灰的重要途径之一。本文利用电子显微镜、氮气吸附仪、X射线衍射等方法系统探索了稻壳灰的结构特征及其物理化学性质,以及稻壳的燃烧制度与稻壳灰活性的关系。为在工业炉中燃烧稻壳,产生最佳活性的稻壳灰提供理论依据。更多还原

【Abstract】 Rice husk ash(RHA), a burned rice husk, can possess superior useful prop erties under certain regular burning condition. RHA can be used as a pozzolanic additive to Portland cement. The structural characteristic and the physical and chemical properties of RHA as well as the influences of combustion conditions on the reactivity of RHA were studied in this report by particle size analysis, SEM, BET, XRD etc.. The results can be used as theoretical reference in the design of industrial furnace for burning rice husk.更多还原
