METHOD FOR PRODUCING REPRODUCED WASTE MATERIAL COMPOSITION AND REPRODUCED WASTE MATERIAL COMPOSITION
To provide an effective technique that can make a processed product itself be a reusable useful composition through a simple and easy process, by being processed without using means for separating a required material from rubble including waste building materials almost regarded the same as wastes.SOLUTION: A production method for a reproduced waste material composition includes: an addition step (A) for an addition agent that is executed before a step (B) or after the step (B) and before a step (C); the heating step (B) that heats a waste gypsum board to obtain a heating treatment product; and the subsequent step (C) that is executed after the step (B). The mixed powder is obtained which has added to precursor powder containing an oxidation silicon component and a material containing a calcium component derived from another material different from the waste gypsum board, which reacts with an oxidation silicon component contained in the precursor powder, in the step (A); anhydrous gypsum is obtained as the heating treatment product in the step (B); and gypsum-tobermorite based material is obtained by hydrothermally treating a solidification body given from the mixed powder at the temperature of 120°C to 350°C in the subsequent step (C).SELECTED DRAWING: None
【課題】大部分が廃棄物とされてきた廃建材を含む瓦礫から、所要の素材を分離する手段を用いることなく処理して、処理物自体を再利用可能な有用な組成物に、簡便で容易なプロセスによってできる効果的な手法を見出すこと。【解決手段】廃石膏ボードを加熱して加熱処理物を得る加熱工程(B)と、工程(B)の後に行う後工程(C)と、工程(B)の前、或いは、工程(B)の後で且つ工程(C)の前に行われる添加剤の添加工程(A)とを有し、工程(B)で加熱処理物として無水石膏を得、工程(A)で、酸化ケイ素成分を含有する原料粉と、該原料粉中の酸化ケイ素成分と反応する、廃石膏ボードとは別の材料由来のカルシウム成分を含有する材料とが添加された混合粉を得、後工程(C)で、混合粉から得た固化体を120℃〜350℃の温度で水熱処理して、石膏−トバモライト系素材を得る再生廃材組成物の製造方法。【選択図】なし
