IMPROVED SLAG FROM NON-FERROUS METAL PRODUCTION
The invention relates to the use of slag as a filler and/or binder in concrete or cement in the construction industry, as a black hard block, and/or as a high-density ballast. The invention relates to slag comprising, in dry basis and in the sum of metals present in elemental metals and metals present in oxidation states: a) at least 7% wt and at most 49% wt Fe; b) up to 1.3% wt Cu; c) at least 24% wt and at most 44% wt SiO2; d) CaO of at least 1.0% wt and at most 20% wt; e) at least 0.10% wt and at most 1.50% wt of Zn; f) MgO of at least 0.10% wt and at most 2.5% wt; and g) up to 0.100% wt of Pb.
本发明涉及一种炉渣在建筑行业中在混凝土或水泥中用作填料和/或粘结剂、用作黑色硬块体，和/或用作高密度压载物的用途。以干基计并且以元素金属存在的金属和氧化态存在的金属的总和表示，所述炉渣包括：a)至少7％wt且至多49％wt的Fe；b)至多1.3％wt的Cu；c)至少24％wt且至多44％wt的SiO2；d)至少1.0％wt且至多20％wt的CaO；e)至少0.10％wt且至多1.50％wt的Zn；f)至少0.10％wt且至多2.5％wt的MgO；和g)至多0.100％wt的Pb。
