METHOD FOR PRODUCING SINTERED BODY HAVING CARBON DIOXIDE ABSORBED
To provide a method for producing a sintered body having carbon dioxide absorbed, which can, when producing the sintered body having carbon dioxide absorbed by using a mixture obtained by mixing coal ash and a Ca source such as waste concrete and the like, suppress decomposition, during sintering, of a state where carbon dioxide is being absorbed as calcium carbonate and also suppress release of carbon dioxide by burning of unburnt carbon contained in fly ash.SOLUTION: When producing a sintered body having carbon dioxide absorbed by irradiating a mixture, obtained by mixing coal ash (for example, fly ash) with a Ca source (for example, waste concrete), with microwave under a carbon dioxide atmosphere to raise the temperature to a sintering temperature or higher, the temperature is configured to be raised by a magnetic field of microwave.SELECTED DRAWING: Figure 2
【課題】石炭灰と廃コンクリート等のＣａ源とを混合させた混合物を用いて二酸化炭素を吸収させた二酸化炭素吸収焼結体を製造するに当たり、焼結時に炭酸カルシウムとして吸収された状態が分解されることを抑制し、また、フライアッシュに含まれる未燃炭素の燃焼により二酸化炭素が放出されることを抑制することが可能な二酸化炭素吸収焼結体の製造方法を提供する。【解決手段】石炭灰（例えば、フライアッシュ）に対してＣａ源（例えば、廃コンクリート）を混合させた混合物に二酸化炭素雰囲気下でマイクロ波を照射させて焼結温度以上に昇温させることで二酸化炭素吸収焼結体を製造するに当たり、混合物を、マイクロ波の磁界による加熱によって昇温させるようにした。【選択図】 図２
