    PROBLEM TO BE SOLVED: To provide a recycle slag capable of being used for a base of buildings or structures low in reaching expandability and excellent in long term stability.SOLUTION: The recycle slag 8 is a slag discharged in a refining process, has a composition of the slag is CaO:30 to 50%, SiO:18 to 40%, T.Fe:3 to 25%, AlO:5% or less, MgO:5% or less and basicity (C/S) of 2.5 or less and 0.58A+0.46B≤20, where A (%) is amount of a CaO-FeO-based mineral phase and B (%) is amount of a β-2CaO-SiOphase in the slag.SELECTED DRAWING: Figure 1

    【課題】到達膨張性を低くし、長期安定性に優れる建築物や構造物の基礎に使用可能なリサイクルスラグを提供する。【解決手段】本発明にかかるリサイクルスラグ８は、精錬工程で排出されたスラグであって、前記スラグの組成が、CaO：30〜50%、SiO2：18〜40%、T.Fe：3〜25%、Al2O3：5%以下、MgO：5%以下であり、且つ塩基度(C/S)が2.5以下のスラグにおいて、前記スラグ中のCaO-FeO系鉱物相の量（A(%)）、β-2CaO-SiO2相の量（B(%))が、「0.58A+0.46B≦20」を満足する。【選択図】図１
