摘　　要：采用煅烧法和蒸压法对化学石膏进行处理,研究了处理温度和外加剂对石膏性能的影响。通过2*6析因实验方法对掺加石膏、水泥、木质素纤维、消泡剂和可再分散胶粉对石膏基自流平材料的性能影响进行了研究,另外还研究了不同晶形转化剂对自流平材料性能的影响。Study on utilizing desulphurization gypsum and phosphogypsum to produce self-leveling material was carried out. The effects of treatment temperature and additives on the property of gypsum were studied. At the .same time, the effects of gypsum, cement, redispersionable glue-powder （RGP）, deformer and lignin cellulose on the property of self-leveling material were also studied. 2 ＊ 6 factorial design experiment method was adopted and the results of experiment were analyzed by variance analysis. Moreover, the influence of the treatment of chcmical gypsum by different additives on self-leveling material was studied.
