FINE BUBBLE-CONTAINING SOLIDIFIED BODY AND METHOD FOR PRODUCING FINE BUBBLE-CONTAINING SOLIDIFIED BODY
To provide a solidified body that allows reuse of a larger amount of waste paper and has improved heat insulating properties, and to provide a method for producing the same.SOLUTION: A solidified body 10 comprises base material 12 solidified by hydration reaction of a cement-based solidifier with water and a fiber 11 derived from waste paper that is dispersed in the base material 12, the solidified body additionally comprising not less than 100,000 fine bubbles 13 having a diameter of 100 μm or less per cubic centimeter in the base material; and preferably based on the cement-based solidifier of 100 pts.wt., having a solidifier containing aluminum sulfate included in a range of 20 to 30 pts.wt., and including a step of mixing the cement-based solidifier with a slurry obtainable by dissolving waste paper into water, a step for including not less than 100,000 fine bubbles 13 having a diameter of 100 μm or less per cubic centimeter of moisture, and a step in which the slurry is allowed to cure until it solidifies.SELECTED DRAWING: Figure 1
【課題】より多くの古紙を再利用することができ、断熱性を向上させた固化体、及びその製造方法の提供。【解決手段】セメント系固化材と水分の水和反応により固化した基材１２と、基材中に分散する古紙由来の繊維分１１とを含む固化体１０において、直径１００μｍ以下のファインバブル１３を基材１立方ｃｍ当たり１０万個以上さらに含み、好ましくは、セメント系固化材１００重量部に対して、２０〜３０重量部の範囲に含まれる硫酸アルミニウムを含む固化材であり、古紙を水に溶いて得られるスラリーにセメント系固化材を混合させる工程と、直径１００μｍ以下のファインバブルをスラリー中の水分１立方ｃｍあたり１０万個以上含有させる工程とスラリーが固化するまで養生する工程を備えるファインバブル含有固化体の製造方法。【選択図】図１
