【摘要】 本文研究了国内钢厂的转炉渣、平炉渣和电炉渣中 MgO、FeO、MnO的结晶状态,并在各种压蒸条件下(温度达330℃、压力则至127个大气压)研究了它们与水化合的能力及其对水泥石膨胀的影响。研究发现,以固溶状态存在的某些MgO比纯方镁石稳定得多。不会引起体积安定性不良。这一结论对于利用钢渣制造钢渣水泥,用作混合材以及用作混凝土骨料是具有现实意义的。更多还原

【Abstract】 The crystalline state of MgO, FeO and MnO in converter slag, open-hearth slag andelectric furnace slag from steel plants were studied and their reactivity with water undervarious autoclave conditions (at the temperature up to 330℃ corresponding to the pre-ssure of 127 atm) were determined. Results show that MgO presenting as solid solution with FeO and MnO is much moreinert than pure periclase and will not cause unsoundness. It is praticable for using steelslag to make steel slag cement or as cement additives and as aggregates of concrete.更多还原
