摘要
探讨了钢渣膨胀的原因,分析了钢渣骨料作建筑工程骨料在混凝土中膨胀破坏的原因及风险。列出了钢渣与天然砂石料在外观、物理特征、矿物和化学成分等方面的区别,表观密度和磨细后的pH值可以鉴别钢渣。
The reason of steel slag expansion is discussed,and the reason and risk of steel slag aggregate expansion failure in concrete as aggregate are analyzed.The differences between steel slag and natural aggregate in appearance,physical characteristics,mineral and chemical composition are listed.The apparent density and pH value after grinding can identify steel slag.
