复合激发激发剂对硬石膏基粉刷石膏水化硬化性能的影响摘要粉刷石膏是以天然硬石膏(?型无水石膏)为主要原料,通过加入复合激发剂进行改性处理,调节凝结时间和抗压抗折强度,然后辅以保水剂、粉煤灰引气剂等,磨细混匀后可以得到抹灰用的粉刷石膏。本实验用天然硬石膏为主要原料,通过加入不同的复合激发剂,测定其水化率)凝结时间)抗压抗折强度等,选择最优配合比。对比实验表明各种指标均优于天然硬石膏。经测试,粉刷石膏的各项技术性能指标均符合国家行业标准要求,强度、:天然硬石膏粉刷石膏激发剂水化率I安徽建筑工业学院本科生毕业论文AbstractTakingnaturalanhydrate(anhydrousgypsum?)-retentionagent,(?typeanhydrousgypsum)asthemainrawmaterial,byaddingdifferentactivator,andmeasuredtherateofhydration,settingtimeandstrengthofacertainage,:AnhydritewallplasteractivatorhydrationII复合激发激发剂对硬石膏基粉刷石膏水化硬化性能的影响目录摘要.........................................................................................................IABSTRACT..........................................................................................II目录......................................................................................................III第1章绪论...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
