GEOPOLYMER COMPOSITION, MANUFACTURING METHOD THEREOF, AND REPAIRING METHOD OF CONCRETE STRUCTURE
To provide a geopolymer composition which exhibits a sufficient initial strength even by room temperature curing and short term curing, and has a long pot life.SOLUTION: A geopolymer composition contains a first ingredient, a second ingredient, and a third ingredient. The first ingredient includes an alkali metal salt. The second ingredient has pozzolanic activity and has an electric conductivity difference of 0.4 mS/cm or more. The third ingredient is composed of at least one slag selected from the group consisting of blast furnace slow cooling slag, converter slag, electric furnace oxidized slag, and molten iron pretreated slag.SELECTED DRAWING: None
【課題】常温硬化及び短期養生で初期強度を発現し、可使時間が長いジオポリマー組成物を提供すること。【解決手段】ジオポリマー組成物は、第１の成分と、第２の成分と、第３の成分と、を含む。第１の成分は、アルカリ金属塩を含む。第２の成分は、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３の成分は、高炉徐冷スラグ、転炉スラグ、電気炉酸化スラグ、および溶銑予備処理スラグから選ばれる少なくとも１つのスラグからなる。【選択図】なし
