Abstract
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.
