<p>PROBLEM TO BE SOLVED: To manufacture a high-quality solidified body which is not affected by a change, such as pozzolan reactivity and plasticity threshold, of coal ash, has stable quality and is assured in safety. SOLUTION: This method manufactures the solidified body by adding additive materials, such as coal and gypsum, to the coal ash and kneading the mixture with water, then subjecting the mixture to molding followed by curing, in which the basicity of an ash content and/or amount of R2O is calculated in accordance with a coal mixing ratio from the database of the ash composition of the coal and the volume of the kneading water and/or the amount of the additive materials is controlled by using a quality controller 64 by this value.</p> |
