PROBLEM TO BE SOLVED: To provide a carbonated cured body which can exhibit sufficient strength while holding a large amount of porous material and has excellent moisture absorption / release properties, adsorbability and decomposability of volatile chemical substances and offensive odors. SOLUTION: The carbonized cured body is composed of calcium carbonate and amorphous silica, the content of amorphous silica is 6% by weight or more, and the nitrogen adsorption specific surface area determined by a specific formula is 25 to 300 m 2 / g. The specific strength is 200 m or more, or consists of calcium carbonate and amorphous silica, and is obtained by a specific formula under the condition that the content of amorphous silica is 6% by weight or more and the relative humidity is 50 to 90%. The weight change rate of the material is 2 to 20%, the specific strength is 200 m or more, or is composed of calcium carbonate, amorphous silica and attapulgite, and the content of amorphous silica is 6 to 40% by weight, or And an inorganic material consisting of 10 to 80% by weight of a porous material (preferably attapulgite) and 20 to 90% by weight of wollastonite is carbonized.
