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。
