PRODUCTION METHOD OF SOLIDIFIED BODY
To provide a method for producing a solidified body, which contributes to reduction of environmental load and contributes to effective regeneration and utilization of slag accumulated as industrial waste.SOLUTION: A method for producing a solidified body comprises kneading steel slag (steelmaking slag and granulated slag), blast furnace slag fine powder, and kneaded water containing chloride ion and sulfate ion to produce the solidified body. In the method for producing the solidified body, reinforcing fibers may be kneaded. The steel slag is used as an aggregate. The aggregate may be composed of the steel slag only, or a fixed amount (for example, 10-20 wt.%) of the aggregate may be replaced with natural stone or natural sand.SELECTED DRAWING: None
【課題】環境負荷軽減に寄与し、産業廃棄物として蓄積されているスラグの有効再生活用に資する固化体の製造方法を提供すること。【解決手段】本発明に係る固化体の製造方法は、鉄鋼スラグ（製鋼スラグ、水砕スラグ）と、高炉スラグ微粉末と、塩化物イオン及び硫酸イオンを含む混練水とを混練し、固化体を製造することを特徴とする。上記固化体の製造方法において、補強繊維を混練してもよい。鉄鋼スラグは骨材として用いるものであり、骨材として鉄鋼スラグのみを用いてもよいし、その一定量（例えば１０～２０重量％）を天然石や天然砂等で置換してもよい。【選択図】なし
