| 摘 要： | 通过酸溶、X射线衍射、红外光谱和扫描电镜等手段分析了粉煤灰石灰蒸压系统中水化产物的变化。结果显示,水榴石在蒸压过程中处于不断变化的状态。水榴石转化为水化硅酸钙时同时存在两种不同形貌的物相,一种是晶粒周围出现的细小纤维状水化产物,还有一种是在大量水榴石周围出现的较大体积类板状含A l高碱水化产物。若系统提供Ca2 的量相对不足,水化产物以细小的纤维状形式存在。若水榴石大量分解,形成无定形高碱水化产物,水化产物可逐步发育为结晶良好的水化硅酸钙。

| Abstract: | Analyzed the change of hydrate in autoclaved fly ash lime system with acid dissolve,X-ray Diffraction(XRD),Infrared Spectroscopy(IR) and Scanning Electron Microscope(SEM).The experimental result showed,hydrogarnet change endlessly in autoclaved condition.Hydrogarnet translate into calcium silicate hydrate,and the hydrate has two types: fine fibrous hydrate and plate high alkali hydrate-bearing Al.The hydrate is fine fibrous hydrate when Ca~(2 )] is lacking in the system.The hydrate is plate high alkali hydrate-bearing Al and could form well crystallized tobermorite when hydrogarnet break down largely. |
