摘　　要：本文采用定量相分析法测定灰砂系统水热反应的水化物,并通过SEM观察及试块强度测定等研究了灰砂系统水热反应动力学。根据实验结果将灰砂系统水热反应进程划分为4个阶段,从而提出了新的反应机理,并进一步讨论了灰砂反应机理的4种性质,以期使目前关于灰砂反应机理的争论趋向统一。Kinetics of hydrothermal reaction in lime-sand system was investigated by means of quantitative phase analysis, SEM observation, and compressive strength measurement. From the experimental results, the hydrothermal reaction of lime-sand mixture can be divided into four stages, and a new hypothesis of reaction mechanism is proposed. Four characteristics of the mechanism are further discussed, hoping that the controversies on the reaction mechanism could be unified by this new suggestion.
