METHOD FOR PRODUCING HARDENED BODY
To provide a new method for producing a hardened body capable of reducing carbon dioxide emissions, including a raw material production process, and effectively utilizing natural resources in Japan.SOLUTION: A method for producing a hardened body includes the steps of: heating and mixing volcanic glass material derived from volcanic ejecta with an alkaline solution and further adding inorganic acid to obtain an active suspension; obtaining a mixture of the active suspension, aggregate, and a calcium source; and filling the mixture into a mold, and then forming, demolding, and curing the mixture, wherein the active suspension includes aluminosilicate-activated particles and aluminosilicate sol.SELECTED DRAWING: None
【課題】原料の製造プロセスを含めて二酸化炭素の排出を削減することができ、国内の天然資源を有効活用することができる新規な硬化体の製造方法を提供する。【解決手段】火山噴出物由来の火山ガラス質をアルカリ溶液と加熱混合し、更に無機酸を加えた活性懸濁液を得る工程と、前記活性懸濁液と骨材とカルシウム源との混合物を得る工程と、前記混合物を型枠に充填し成形し、脱型し、養生する工程と、を有し、前記活性懸濁液がアルミノけい酸賦活粒子とアルミノけい酸ゾルとを含む硬化体の製造方法。【選択図】なし
