  1. Autoclave method for soundness of portland cement

    水泥壓蒸安定性試驗方法
  2. Boiling testing box for soundness of the portland cement

    水泥安定性試驗用沸煮箱
  3. Le - chatelier apparatus for soundness test of the portland cement

  4. Effect of mgo, f - cao, feo, ro phase and metal fe in steel - making slag powder on soundness of cement is investigated by boiling test, steam test and autoclave test

    採用沸煮、高溫長時間蒸養及壓蒸方法研究了鋼渣粉中的f - cao 、 mgo 、 feo 、 ro相及金屬鐵對水泥安定性的影響。
  5. Results show that mgo, feo, ro phase in steel - making slag do not cause soundness problem of cement. generally speaking, f - cao and metal fe are main factors which cause soundness problem of steel - making slag powder, so their content must be limited strictly restricted. content of f - cao must be limited fewer than 3 % and content of metal fe must limited fewer than 2 %

    實驗結果表明，摘要鋼渣粉中的mgo 、 feo 、 ro相一般不會引起水泥安定性不良的問題;氧化鈣及金屬鐵是影響鋼渣粉安定性不良的主導因素，應用中要嚴格控制它們的含量，鋼渣粉中的游離氧化鈣宜控制在3 %以內，金屬鐵含量宜控制在2 %以內。
  6.
