As the free cao in mgo - gao refractories is easy to be hydrated , lots of work has been done to solve the problem with useful results having been obtained
镁钙系耐火材料的弱点是其中游离氧化钙易水化的问题，围绕着这一问题，人们做了大量的工作并取得了一些有益的结论。
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 %
实验结果表明，摘要钢渣粉中的mgo 、 feo 、 ro相一般不会引起水泥安定性不良的问题;氧化钙及金属铁是影响钢渣粉安定性不良的主导因素，应用中要严格控制它们的含量，钢渣粉中的游离氧化钙宜控制在3 %以内，金属铁含量宜控制在2 %以内。
