HYDRAULIC COMPOSITION, HYDRAULIC COMPOSITION MIXED MATERIAL, AND HARDENED BODY
The present invention addresses the problem of proposing: a hydraulic composition which is capable of stably holding and storing CO2 recovered from the atmosphere, while being reduced in the cost; and a hardened body which is formed from this hydraulic composition. The present invention is a hydraulic composition which contains calcium carbonate. The proportion of the calcium carbonate in the materials is within the range of from 30% by mass to 95% by mass. In addition, this hydraulic composition contains at least one substance that is selected from among blast furnace slag, expansive admixture, slaked lime, calcined lime, fly ash and Portland cement. Incidentally, in cases where Portland cement is contained therein, the proportion of the Portland cement in the materials excluding the calcium carbonate is 30% by mass or less. In cases where expansive admixture is contained therein, the proportion of the expansive admixture in the materials is from 2% by mass to 9% by mass.
