摘要
使用化学纯试剂Ｈ２ＳｉＯ３、ＣａＯ为原料，在常压１００℃的条件下，分别合成了钙硅比（Ｃ／Ｓ）等于１．０，１．５和２．０的ＣＳＨ相，探讨了β－Ｃ２Ｓ在ＣＳＨ相脱水过程中的形成温度和形成速度，同时对于Ｃ／Ｓ＝１．０和１．５的两个体系，我们在样品中补充部分ＣａＣＯ３，进一步探讨了由β－ＣＳ＋ＣａＯ→β－Ｃ２Ｓ转化的速度。
CSH phase of 1.0, 1.5 and 2.0 C/S ratio was produced respectively at 100 ℃ hydrothermal condition, using raw materials of chemical pure H 2SiO 3 and CaO. The formation temperature and formation speed of β C 2S in the dehydration process of CSH phases were discussed. An amount of CaCO 3 was mixed with CSH phases of 1.5 and 2.0 C/S ratio, the formation speed of β CS+CaO→ β C 2S in the dehydration process of these mixed materials was studied. The amount of β C 2S was quantified with QXRD.
