SLAG SHAPED BODY AND SLAG SHAPED BODY PRODUCTION METHOD
To provide a slag shaped body having excellent handleability and capable of stable and efficient elution of iron in an aqueous environment.SOLUTION: A slag shaped body (1) comprises: a steel slag (2); and an accessory material (5) having an acidic functional group and supplementing the elution of iron in an aqueous environment by reacting the acidic functional group with the iron contained in the steel slag (2), where the slag shaped body contains 50 μmol/g or more of the acidic functional group.SELECTED DRAWING: Figure 1
【課題】取扱性が良好であり、安定的かつ効率的に鉄を水環境中に溶出させることができるスラグ成形体を提供する。【解決手段】スラグ成形体（１）は、製鋼スラグ（２）と、酸性官能基を有し、酸性官能基と製鋼スラグ（２）に含まれる鉄との反応により水環境中における鉄の溶出を補助する補助物質（５）と、を含み、酸性官能基を５０μｍｏｌ／ｇ以上含有する。【選択図】図１
