摘要
通过实验研究了缓凝剂、掺材及保水剂对 β半水型粉刷石膏性能的影响。缓凝剂对 β半水膏的缓凝效果 :柠檬酸 >柠檬酸钠 >酒石酸 >酒石酸钾钠 >蔗糖 >磷酸盐。所加入的矿渣及水泥熟料可以提高粉刷石膏的强度。保水剂的保水率 :MC >CMC >钠基膨润土。
The influences of retarders,admixtures and water retention agents on the performance of β-hemihydrate gypsum plaster were study by a series of experiments in this paper.The results showed that the retarding effect of the retarders is citric acid>sodium citrate>tartaric acid>potassium sodium tartrate>sugar>phosphate.The steel slag and cement clinker added in the gypsum plaster increased the strength of the material.The water retention effect of the water retention agents is MC>CMC>Na-montmorillonite.
