【摘要】 研究了含有氟硫的高含量MgO水泥的压蒸膨胀和MgO在高温液相中的溶解。结果表明,SO₃降低MgO在液相的中的溶解度;掺CaF₂+SO₃后,低温烧成的高MgO水泥的压蒸膨胀率大于0.5％。更多还原

【Abstract】 Emphasis is put on autoclave expansion of high MgO cement with mineralizer, and dissolution of MgO in liquid phase at high temperature. The result shows that the solubility of MgO in liquid phase is reduced by SO₃, and the autoclave expansion of high MgO cement added with CaF₂+SO₃, burnt at lower temperature, exceeds 0.5％.更多还原
