【摘要】 本文实验研究了轻烧白云石的烧制工艺，在650～750℃下．恒温1～2h制得的轻烧白云石，其活性氧化镁含量在12～13％范围内，以此为原料，制得的氯氧镁水泥快凝早强，试件1天抗析强度高达15MPa以上，7天抗折强度在9～12MPa。更多还原

【Abstract】 The sintering process for lightly-burnt dolomite is studied by experiments.The content or the magnesium oxide in lightly - burnt domolite produced at the temperaturc of 650-750℃ and undcr a constant pressure of 1-2 hours is in the range of 12 - 13%.The magnesium oxycNoride cement produced with lightly-burnt dolomite as the raw material features quick-setting and early strength.The 1 - day bending strength or the specimens is up to 15 Mpa and the 7 - day bending strength is 9-12Mpa.更多还原
