Experimental Study on Ionic Soil Stabilizer Reinforcing Red Clay

Abstract:

In this research, a kind of Ionic Soil Stabilizer (ISS for short) is used as great extension of Ministry of Water Resources of the People’s Republic of China. Based on the red clay of Hanyan district of Wuhan reinforced by Ionic Soil Stabilizer, the red clay soil is treated by different matches of ISS and water at first, then is tested in the Atterberg limits test, dirct shear test and surface tension test. The results show that the plastic index decreases, and the cohesion increases after mixing the ISS into the red clay. In addition, Once ISS is dissolved in water, it can reduce the surface tension of water, and with the concentration increasing, the surface tension decreased. Finally the mechanism how ISS reinforces the red clay is analyzed by the aspect of the structure of pair-electricity layer and the Zeta potential.
