This study provided a basis for new possibilities concerning the use of the sugarcane bagasse ash as a green pozzolanic addition to the Portland cement composite. To that effect, a simple micronization method using air jet milling without any other additional thermal procedure was used to control the characteristics of ash particles. This procedure not only maintains the required characteristics of the residues but can also improve some of them. Sugarcane bagasse ash is a residue produced on large scale in Brazil by ethanol and sugar plants as a result of the burning of sugarcane bagasse in energy cogeneration. The residue used in this study was initially characterized by scanning electron microscopy, granulometric and specific mass analyses, N₂ adsorption measurements, X-ray diffraction, X-ray fluorescence spectroscopy, and thermogravimetric analysis with differential thermal analysis. Pozzolanic ash activity was evaluated according to the axial compressive strength at 28 days and the modified Chapelle methods. The results showed that the milling fly sugarcane bagasse ash samples presented satisfactory pozzolanic activity.

使用喷气磨将巴西甘蔗渣微粉化，用于绿色Pozzolan

这项研究为使用甘蔗渣粉作为波特兰水泥复合材料的绿色火山灰添加物提供了新的可能性。为此，使用了一种简单的使用气流粉碎的微粉化方法，而没有任何其他额外的加热程序来控制灰分颗粒的特性。该方法不仅可以保持所需的残留物特征，还可以改善其中一些残留物。甘蔗渣灰是在巴西的乙醇和制糖厂在能源热电联产中燃烧甘蔗渣而大量生产的残渣。本研究中使用的残留物最初通过扫描电子显微镜，粒度分析和比重分析（N _2）进行表征吸附测量，X射线衍射，X射线荧光光谱和差示热分析的热重分析。根据28天的轴向抗压强度和改进的Chapelle方法评价火山灰的活性。结果表明，粉磨甘蔗蔗渣灰分样品具有令人满意的火山灰活性。
