摘要
采用扫描电镜、X射线衍射以及差热-热重分析技术研究了石灰石粉在超高性能水泥基材料中的作用机理。研究表明,在高温蒸养的条件下,石灰石粉的水化活性及加速水化效应比较明显,水化生成单碳水化碳铝酸钙和三碳水化碳铝酸钙;在配制超高性能水泥基材料时,掺量为10%的石灰石粉对强度的影响较小,可以降低材料成本。
The functionary mechanism of limestone powder in ultra high performance cement-based composites was studied by using scanning electron microscopy （SEM）, X-ray diffraction （XRD） and DTA-TG analysis. The results show that the hydration activity and the accelerating effect of limestone powder are obvious under the condition of high temperature and hydrated and formed calcium monocaboaluminate hydrates. When limestone powder content is 10% for preparing ultra high performance cement-based composites, there is little influence on compressive strength, which can reduce the cost.
