| 摘 要： | 利用不同含泥量的硅质石屑作为硅质材料与石灰钙质材料进行水热合成反应制备B05、B06级加气混凝土。通过配合比设计、发气研究、加气混凝土性能测试，得出了用不同含泥量石屑制备加气混凝土的适宜配方及关键工艺参数；并通过XRD、SEM等测试手段，探讨了含泥硅质石屑-石灰加气混凝土的微观结构。研究结果表明，含泥硅质石屑-石灰体系水热合成反应后，水化产物为低结晶度的水化硅酸钙、托贝莫来石和水石榴石，并形成了均匀密实的加气混凝土结构。

| Abstract: | This paper reports the study about using of clayish crushed stone for making aerated concrete. Through studying hydro-thermal synthesis reaction, mix ratio, gas-forming and performance analysis, B05 and B06 grade aerated concrete were prepared successfully. The proper mix ratio and key processing parameters were achieved. The microstructure of aerated concrete with crush stone was analyzed by means of modern analysis means such as XRD and SEM. The results indicate that the hydration products are poorly crystalline C-S-H (B), tobermorite and hydrogarnet. The structure system of aerated concrete is homogeneous and density. |
