HYDRAULIC COMPOSITION, HARDENED BODY, AND METHOD FOR PRODUCING HYDRAULIC COMPOSITION
To provide a low-carbon hydraulic composition which is produced using an inorganic mineral other than kaolin and has sufficient compressive strength development.SOLUTION: A hydraulic composition contains: 10 to 90 mass% of a calcined inorganic mineral that is a calcined product of an inorganic mineral having a mass ratio of trivalent iron ions to divalent iron ions (Fe3+/Fe2+) of 2.0 to 6.0 as measured by absorptiometry, and has a mass ratio of SiO2 to Al2O3 (SiO2/Al2O3) of 0.5 to 3.0, based on the total amount of the calcined inorganic mineral and an alkali stimulant; and 10 to 90 mass% of the alkali stimulant based on the total amount of the calcined inorganic mineral and the alkali stimulant.SELECTED DRAWING: None
