A Quantitative Study of Microstructure Characteristics of Ionic Soil Stabilizer Reinforcing Red Clay

Abstract

In order to improve the red clay’s undesirable physical properties, improve its strength and reduce deformation, use a new type of electrochemical reinforcement imported from Australia —Ionic Soil Stabilizer, to make reinforcement on the red clay in Wuhan and then microstructure and quantitative research of red clay was explored. First, ISS with different volume ratio of water and then adding different proportions of red clay ISS solution, the unconfined compressive strength test and scanning electron microscope analysis test. As it can be seen from the results that after ISS reinforces the red clay, unconfined compressive strength Obviously increases; the main types of microstructure change to be the aggregate structure, however, aggregate apparently turn to be bigger and correspondingly void volume decrease with a denser structure. On the base of fractal theory, the 3000-times SEM photographs were vectored by ARCGIS, and then quantitatively analyzes variation of soil pore.
