| Abstract: | As a consequence of study on the activation method of flyash,the most suitable activator HR and corresponding activation condition were determined. Various methods,including XPS,IR,TEM,TGA and DTA,were applied to research into the surface ingredients,radicals and morphology of activated flyash;and the hydrophobicity of flyash and its dispersivenes and affinity in organic media were also investigated. These lead to the conclusion that the molecules of activator tightly stick to the surface of flyash by chemical bonds,thus obviously modifying its property. |

| Keywords: | flyash activation surface modification structural analysis surface property |
