粘土固化浆液固结过程的SEM研究

SEM study of hardening processes of clay hardening grouts

分析了粘土固化浆液中各组分的水化反应过程以及固化剂的催化机理，用ＳＥＭ方法研究了粘土固化浆液固结过程中的中间产物和反应产物的微观结构，证实了固化剂的催化机理。在此基础上，提出了粘土固化浆液的固结模型。

The hydrous reaction processes of each component of clay hardening grouts (CHG) and catalytic mechanics of the hardening agent in the CHG have been studied and analyzed in the paper. The microstructure of the reaction products and intermediate products in hardening process of CHG are studied with scanning electron microscopy (SEM). The catalytic mechanics of hardening agent has been proved. On the basis of the analysis and study, the hardening model of clay hardening grouts is proposed.
