【摘要】 通过用芒硝石膏替代天然石膏作为水泥缓凝剂的技术研究和试验,证明芒硝石膏可以替代天然石膏,同时可提高水泥早期强度;芒硝石膏的最佳掺量为5%~7%;芒硝石膏的CaSO4含量应保持相对稳定。更多还原

【Abstract】 Through the technological research and experiment of replacing natural gypsum with glauberite as cement retarder,it is proved that natural gypsum can be replaced by glauberite and meanwhile the early strength of the cement be improved.The optimal dosage of glauberite is 5%-7% and the CaSO4 content in the glauberite should be kept stable.更多还原
