The solidified agent on with particular characteristics was used as a new kind of additive for solidi- fying fly ash. Unconfined compression strength tests were carried out to analyze the effects of solidified agent content and curing period. The variation law of the various components of the solidified fly ash during the for- mation of strength was discussed on the basis of X-ray Diffraction (XRD) test s of solidified fly ash; scanning electron microscope (SEM) was used to analyze the microstructure formation process and microstructure char- acteristics of the solidified fly ash; Result s of analysis on the basic principle of reactions between the fly ash and lime were the basis of the proposed solidified fly ash reinforcement mechanism, which provides theoretical and practical foundation for further application of solidified fly ash.
