摘要
研究了骨胶蛋白质石膏缓凝剂对石膏凝结时间和强度的影响。结果表明,骨胶蛋白质石膏缓凝剂不仅能够有效地延长石膏的凝结时间,而且对石膏的强度影响较小。通过对石膏硬化体微观晶体形貌的观测研究,分析了骨胶蛋白质石膏缓凝剂对石膏强度影响较小的原因。
The effect of bone glue protein retarder on setting time and strength of gypsum is studied. The results show that the bone glue protein retarder can not only effectively prolong the setting time of gypsum but also has little influence on strength of gypsum which is analyzed by means of observing the crystal morphology microstructure of gypsum.
