In this paper, environmental assessment has done for incineration residue by the case study on coal fly ashes. As the result of comparison between each experiment for analysis of materials or leaching tests, there is the problem to using the monolithic model for the chemical assessment of coal fly ashes. By the reason that coal fly ash are mixture of 3 components “Water solubility Part” which soon move after contact with water, and “High surface areas Part” which make absorption or desorption in metastable in any hours, and “Part of leaching availability (eg: after pozzolanic reaction) ” which any insoluble part would be changed for soluble part in future. So, we propose: it is necessary to continue the experiment of this study.
