摘    要:
研究了氧化钙、树脂胶、硫酸钾、硼砂等添加剂对普通模型石膏及人造石性能的影响。结果表明:氧化钙、树脂胶、硼砂均能延长固化时间,降低混水率并提高抗压强度;硫酸钾能加速凝固反应速率,缩短凝固时间。

关 键 词:添加剂  石膏  性能

Abstract:
In this study, the influence of adding agent were investgated. These adding agents include: Calcium oxide, Gum acacia powder, Potassium sulfate, Sodium borate etc. These experimental results show thatcalcium oxide , Gum acacia powder, Sodium borate extend the setting time, raise the compressive strength and reduce the water/power ratio. Potassium sulfate accelerate the speed of the reaction, thus it reduce the setting time.
Keywords:adding agent plaster property
