EN-1固化土体的微观特性的试验分析

Experimental Analysis of Microcosmic Characteristics of EN-1 Solidified Soil

为探究EN-1固化剂的材料属性及固化土的微观固化机理。本文采用IR spectrum、elemental analysis、X射线衍射测试、比表面积测试、SEM等微观试验来分析。研究结果表明:EN-1固化剂含有C、N、H三种元素,总含量很少,其固化剂土体未产生新的矿物。EN-1固化剂内含链式结构,可提高土颗粒的粘结力。随着EN-1掺量增加,比表面积减小,但固化土体强度增强。

In order to explore the material properties of EN-1 curing agent and the micro solidification mechanism of solidified soil,this report were analyzed by infrared spectroscopy, elemental analysis, XRD test, specific surface area test, scanning electron microscope and other microscopic tests. The research result shows that EN-1 curing agent contains C, N and H., but little total content of them and no new mineral is produced in the solidified agent soil. EN-1 curing agent contains chain structure, which can enhance the cohesive force between soil particles. The more the amount of EN-1, the smaller the specific surface area and the stronger the strength of solidified soil.
