Hydration kinetics and products of MgO-activated slag are investigated by employing multiple analytical characterization techniques and thermodynamic modelling. The main hydration products of this cement are a calcium-aluminosilicate hydrate type gel, ettringite, monosulfate, hydrotalcite, brucite, and a third aluminate hydrate, while the extent of reaction and formation of reaction products significantly varied by MgO dosages. Higher dosage of MgO increased the degree of reaction of slag, and led to a higher population of Al in the octahedral region, which can be attributed to greater competition for Al required for the formation of hydrotalcite. The experimental and simulated volume of the solid binder increased as the MgO dosage increased, showing a good correlation with the strength increase of the samples with higher MgO dosage.

利用多种分析表征技术和热力学模型研究了MgO活化炉渣的水化动力学和产物。该水泥的主要水合产物是钙铝硅酸盐水合物型凝胶，钙矾石，单硫酸盐，水滑石，水镁石和第三铝酸盐水合物，而反应的程度和反应产物的形成因MgO剂量的不同而有很大差异。较高的MgO用量会增加炉渣的反应程度，并导致八面体区域中的Al含量较高，这可以归因于形成水滑石所需的Al竞争更大。随着MgO剂量的增加，固体粘合剂的实验量和模拟量也随之增加，这与MgO剂量较高的样品的强度增加具有良好的相关性。
