| description | PROBLEM TO BE SOLVED: To provide a method for solidification of fly ash wherein eluation of heavy metals in the fly ash can be made to a reference value or lower provided by a law and chemicals used for the treatment are easy to be handled and inexpensive and the burnt exhaust gas can be used as a carbon dioxide source and the price is inexpensive and exhaust of carbon dioxide gas can be decreased and in addition, as the fly ash treated with a sulfate and carbon dioxide is solidified with a hydraulic substance such as a cement, handling after the treatment is easy. SOLUTION: The method for solidification of fly ash comprises adding one or two or more substances among sulfates, aluminum-containing substances and alkaline substances into the fly ash and water, kneading the mixture, blowing carbon dioxide gas and then, adding a hydraulic substance thereinto and kneading the mixture. |
