摘要
为提高硝基石膏使用效果,提升品质,采用不同添加物提高硝基石膏性能。在硝基β石膏粉中掺加添加剂NGM、AGM、SG,发现初终凝固时间明显改善,抗折强度、抗压强度等明显提高,石膏强度明显增加。综合考虑,添加5%NGM与0.05%SG效果最佳。
In order to improve the effect of the use of nitro-gypsum and to improve its quality,different additives can be used to improve the performance of nitro gypsum.Mixed the nitro-βgypsum powder with additives NGM,AGM,SG showed significant improvement in initial and final solidification time,flexural strength,compressive strength and gypsum strength.Add 5% NGM and 0.05% SG have the best effect.
