MOLDING MATERIAL, METHOD FOR PRODUCING MOLDING MATERIAL, MOLDING, AND METHOD FOR MANUFACTURING MOLDING
PROBLEM TO BE SOLVED: To provide: a molding material capable of forming a molding only using a paper making sludge incinerated ash; a method for producing the molding material; a molding using a paper making sludge incinerated ash, excellent in a moldability and high in strength; and a method for manufacturing the molding.SOLUTION: A molding material consists of a paper making sludge incinerated ash obtained by incinerating the residue in a paper pulp producing process. The paper making sludge incinerated ash is controlled so that fine particles having a particle size of 20 μm or less is included at a proportion of 15 volume% or more. Since the fine particles having a suitable size is controlled so as to have a suitable percentage content, the fine particles are solidified only by adding water. Therefore, the molding can be formed when the fine particles are used instead of binders, such as cement and gypsum.
【課題】製紙スラッジ焼却灰だけを用いて成形体を形成することができる成形材料および成形材料の製造方法ならびに製紙スラッジ焼却灰を用いた成形性に優れ、かつ強度が高い成形体および成形体の製造方法を提供する。【解決手段】紙パルプ製造工程残渣を焼却処理して得られる製紙スラッジ焼却灰からなる成形材料であって、製紙スラッジ焼却灰は、粒子径２０μｍ以下の微粒子が、１５体積％以上の割合で含有するように調整されたものである。適切な大きさの微粒子が適切な含有率となるように調整されているので、水を加えるだけで固化させることができる。すると、セメントや石膏などの結合剤に代えて使用すれば、成形体を形成することができる。【選択図】図１
