摘　　要：为了节能环保,充分利用固废,钢渣、钢铁渣粉广泛用于生产建筑材料。钢渣在出厂前需控制MgO含量,以保证用于混凝土砖或砌块时的体积安定性,这些都有相应标准的规定。若混凝土砌块或砖使用了MgO超标的钢渣,则可能在房屋交付使用后给建筑物带来难以修复的危害。因此建议现行混凝土砌块或砖标准中增加相应的检测指标,从而保障房屋结构的正常使用功能。In order to save energy and protect environment and make full use of solid waste,steel slag and ironorsteel slag are widely used in production of building materials.The content of MgO should be controlled before the steel slag leaves the factory,so as to ensure the volume stability when it is used in concrete bricks or blocks.All these are stipulated in the corresponding standards.However,steel slag exceeding the MgO standard used in concrete blocks or bricks may cause irreparable harm to the building after delivery.Therefore,it is suggested to add corresponding test index in the current standard of concrete block or brick,so as to ensure the normal use function of building structure.
