本工作在前文的基础上进一步研究整个MgO-CaO系列材料的活化烧结规律,着重探讨MgO/CaO之比对轻烧-水化试样烧结行为的影响和烧结试样的抗水化性。试验工作证明,天然高纯MgO-CaO系列的两相材料,用轻烧-水化方法,可以在1400℃烧后基本完成致密化过程,在1600℃烧后可得显微结构良好和高度直接结合的MgO-CaO熟料。二端员原料烧结时,晶粒异常长大,密度低,闭气孔率高。轻烧-水化试样的易烧结主要同CaO和MgO对OH-的吸附-脱附作用有关。
This work further studies the activation sintering rules of MgO-CaO series materials on the basis of the previous article, and focuses on the influence of MgO / CaO ratio on the sintering behavior of light-burned-hydrated samples and the hydration resistance of sintered samples. Experimental work proved that the natural high purity MgO-CaO series of two-phase materials, with light burning - hydration method, can basically complete the densification process after burning at 1400 ℃, after firing 1600 ℃ microstructure is good and highly direct Bound MgO-CaO clinker. Two members of the raw material sintering, abnormal grain growth, low density, closed porosity. Light burned - easy hydration of hydrated samples with CaO and MgO on OH - adsorption - desorption.
