Document Type and Number:
Japanese Patent JP2753267
Kind Code:
B2
Abstract:
PURPOSE:To efficiently obtain a good cured body which is uniformly carbonized by subjecting a molding of a mixture contg. a binder to be cured by carbonatation to compression and dehydration with a pressurized gas, then permeating a pressurized carbon dioxide into the molding. CONSTITUTION:The molding 4 of the mixture contg. the binder to be cured by the carbonatation is subjected to the compression and dehydration with the pressurized gas [e.g.: pressurized air or pressurized carbon dioxide is introduced from an upper (a) chamber] and the gas contg. the carbon dioxide is permeated through the molding 4 simultaneously therewith or in succession thereto at the time of carbonating and curing the above-mentioned molding. Since the compression and dehydration of the molding is executed by the pressurized gas according to the above-mentioned method, the molding is adjusted to a uniform moisture content and the efficiency of the carbonatation of the molding is improved. The binder is exemplified by, for example, xonotlite, tobermorite, cement hydrate, slaked lime, magnesium hydroxide, etc.
