| 摘 要： | 研究了掺有少量异组份的C_6AF_2、C_4AF和C_6A_2F的水化活性,早期水化热及c(?)H_2和(或)CH存在条件下的早期水化特性,讨论了石膏的缓凝机理。结果表明,掺有异组份的C_6A_2F具有高的水化活性及快凝快硬性能;石膏延缓水化的作用主要取决于铁相矿物的水化活性及AFt包裹层的状况。

| Abstract: | In this paper, the hydration activity, early heat evolution and early hydration characteristics of C_6AF_2,C_4AF,C_6A_2F doped with small amount of foreign constituents in the presence of CSH_2 and/or CH have been studied. The retarding mechanism of gypsum is discussed. Results show that C_6A_2F doped with foreign constituents possesses high hydration activity and the properties of quick setting and hardening. The retarding effect of gypsum on hydration mainly depends on the hydration activity of ferrite phase and the condition of coating layer formed by AFt phase, |
