论文摘要
作为行业副产品，粉煤灰（FA）作为适当的硅（SI）和铝（AL）引起了很多关注，以为可持续的环境和材料科学应用准备地质聚合物。在这里，通过分析碱溶液中Si和Al离子的大小，表面形态，晶体结构和溶解度，可以系统地研究机械化学（MC）处理FA粉表面修饰FA粉的作用。详细讨论了溶解动力作为MC治疗时间的函数，并以“研磨效果”和“激活效应”的重组模型进行了结论，分别与表面形态和晶体结构的变化良好相关。
Fly ash (FA), as an industry by-product has attracted much attention as a suitable supplier of silicon (Si) and aluminum (Al) in preparation of geopolymer for the sustainable environment and material science applications. Here, the effect of mechano-chemical (MC) treatment for surface modification of FA powder was systemically investigated by analyzing the size, surface morphology, crystal structure and dissolubility of Si and Al ions in alkali solutions. The dissolution dynamic as a function of MC treatment time is discussed in details and concluded with a recombination model of "grinding effect" and "activation effect", which can be well correlated with the change of surface morphology and crystal structure, respectively.
