MANUFACTURING METHOD OF HUMIDITY MODIFIED HOUSING MATERIAL
PROBLEM TO BE SOLVED: To provide a manufacturing method of a humidity modified housing material less in micropore and excellent in humidity modification performance for overcoming a situation that release amount of a cement cured article becomes less than moisture absorption amount when the cement cured article has many micropores, water remains inside where moisture is easy to remain in the cement cured body at a state with storing in the micropores, and warpage or dimensional changes are generated in the cement cured body due to secular change when water remains inside.SOLUTION: A molding material containing cement and water is molded to form a substrate, the substrate is autoclave cured and then a carbonation treatment is conducted. Fine pore with diameter of 5 nm or less (micropore) becomes less. By the treatment, released amount of a cement cured article becomes larger than moisture absorption amount and a moisture modified housing material excellent in moisture modification performance is provided.SELECTED DRAWING: Figure 1
【課題】セメント硬化物が多くのミクロポアを有するとセメント硬化物の放出量が、吸湿量よりも少なくなり、水分がミクロポア内に留まった状態でセメント硬化体内部に残存しやすい。内部に水が残存していると、経年変化により、セメント硬化物に反りや寸法変化が生じることがあった。このため、ミクロポアが少なくて調湿性能に優れる調湿建材の製造方法の提供。【解決手段】セメントと水とを含有する成形材料を成形して基材を形成し、該基材をオートクレーブ養生した後、炭酸化処理を施す。直径が５ｎｍ以下の細孔（ミクロポア）が少なくなる。この処理により、セメント硬化物の放出量が、吸湿量よりも多くなり、調湿性能に優れた調湿建材となる。【選択図】図１
