摘　　要：根据绿色植被混凝土中植物生长对混凝土碱度的要求,采用新型酸性激发剂X激发粉煤灰活性,制备高掺量粉煤灰混凝土;并以化学方法进行降碱处理,制备出低碱混凝土。探索新型酸性激发剂X激发粉煤灰活性的最优工艺、碱度的降低方法,为制备绿色植被混凝土奠定了物质基础。According to plants grow in ecological concrete need moderate pH value, excited activity of fly ash with acidity excitant X, produced high-volume fly ash concrete, and did disposal of depress pH value by chemical method, produced the low-alkalinity concrete. Explored the best technology of fly ash＇s excited activity with acidity excitant X, the method of depress pH value. Establish physical base in order to produce concrete for vegetation.
