The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

本文对高水速凝材料-软土硬化机理的研究表明，高水速凝材料-软土的硬化过程可分为三个阶段：①水化溶解阶段：主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段；②胶凝固化阶段：主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用；③强度增长阶段：钙矾石晶体相互连接，大量吸收周围环境中的水分，并将水分变成自己的结晶水；水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

The mechanism of carbonization process of aluminate solution was analyzed thermodynamically. The results show that the internal reason of precipitation of Al3 in the process is its spontaneous nucleation caused by supersaturation of aluminate solution. The behaviors of SiO2 in the process are in accordance with that from published experiment, which implies that the content of product SiO2 from carbonization depends on its solubility but is not the result of absorption. The thermodynamic calculation for forming Na2O·Al2O3·2CO2· n H2O was achieved.

摘 要：为对高浓度铝酸钠溶液碳酸化分解过程中产品杂质含量的控制提供理论依据，分析了铝酸钠溶液碳酸化分解过程的热力学，认为该过程中Al3析出的真正机理是过饱和铝酸钠溶液的自发结晶；而基于分解过程中平衡浓度的热力学计算表明，在碳酸化分解过程中SiO2的变化规律与公认的三段变化规律一致，说明该过程产品中SiO2的含量取决于它在溶液中的平衡浓度，而非吸附所致；同时还分析了丝钠铝石的形成热力学。
