摘要
AK糖工业废渣——糖石膏的煅烧温度和陈化时间会对石膏浆体性能产生影响,要制备性能良好的建筑石膏,必须在煅烧温度和恒温时间两者之间找出平衡点。通过实验确定,170～180℃煅烧2 h获得的建筑石膏通过三相分析,其主要成分是半水石膏、二水石膏(含量约为2%)、无水石膏(含量<10%)。陈化时间7 d左右为宜,不经陈化或陈化时间过短,其物相组成不稳定,陈化时间过长将出现不凝结现象。
AK sugar industry waste—sugar gypsum＇ calcining temperature and aging time will influnce the performance of gypsum slurry.In order to prepare good building gypsum,the balance between the calcining temperature and constant temperature time must be found.Through three-phase analysis the main component of the building gesso which is prepared at 2 h,170～180 ℃ calcination is the half water gesso,and two water gesso content is 2%,no water gesso content is less than 10%.The suitable aging time is 7 days.
