GEOPOLYMER COMPOSITION, MANUFACTURING METHOD THEREOF, AND REPAIR METHOD FOR CONCRETE STRUCTURE
To provide a geopolymer composition having a long pot life while an initial strength and the like can be maintained in the case of room temperature curing and short-term curing, and a method of producing the same.SOLUTION: The geopolymer composition according to the present invention includes a first component containing an alkali metal salt, a second component having pozzolanic activity and an electrical conductivity difference of 0.4 mS/cm or more, and a third component composed of slag, in which the slag contains 0.1 mass% or more and 5.8 mass% or less of calcium carbonate. And the method of producing the geopolymer composition according to the present invention includes a step of performing a carbonation treatment of slag in an atmosphere having a carbon dioxide concentration of 1% or more, and a step of mixing the first component containing the alkali metal salt, the second component having pozzolanic activity and the electric conductivity difference of 0.4 mS/cm or more, and a third component composed of the slag having undergone the carbonation treatment.SELECTED DRAWING: None
【課題】常温硬化及び短期養生での初期強度等は保持しつつ、可使時間が長いジオポリマー組成物及びその製造方法を提供することを目的とする。【解決手段】アルカリ金属塩を含む第１の成分と、ポゾラン活性を有し、かつ電気伝導率差が０．４ｍＳ／ｃｍ以上である第２の成分と、スラグからなる第３の成分を含み、前記スラグは、０．１質量％以上５．８％質量以下の炭酸カルシウムを含むジオポリマー組成物；ならびに、スラグを二酸化炭素濃度１％以上の雰囲気下で、炭酸化処理を行う工程と、アルカリ金属塩を含む第１の成分と、ポゾラン活性を有し、かつ電気伝導率差が０．４ｍＳ／ｃｍ以上である第２の成分と、前記炭酸化処理を経たスラグからなる第３の成分を混合する工程とを含むジオポリマー組成物の製造方法。【選択図】なし
