Based on the red clay of Wuhan reinforced by Ionic Soil Stabilizer, the red clay soil is treated by different matches of ISS at first, then is tested in the Atterberg limits test and dynamic triaxia test. The results show that the plastic index decreases, and the red clay were greatly improved under the dynamic condition, the maximum dynamic shear modulus ratio acquired an incensement of 27.72% on average after mixing the ISS into the red clay. In addition, It was concluded that the confining pressure influenced the dynamic shear modulus and damping ratio to a certain extent. Given the same strain conditions, with the incensement of confining pressure increases, the dynamic shear modulus increased and the damping ratio decreased. Moreover, when plotting the dynamic shear modulus versus the dynamic shear strain, the similar curve can be formed for both the natural soil and the modified one, the dynamic shear modulus monotonously decreased with the incensement of the dynamic shear strain. However, the value of dynamic shear modulus differed in the same shear strain between the natural soil and the soil modified by ISS.

With fast research and development, economic and effectual materials have been the focal point of all over the world all the time. This experiment studies and uses a new kind of economic and suitable Ionic Soil Stabilizer (ISS for short). Based on the red clay of Wuhan reinforced by Ionic Soil Stabilizer, the red clay is treated by different matches of ISS and water at first, then is tested in the unconfined compressive strength test, shrinkage test, free swell test, and spectrum test. The results show that unconfined compressive strength increases, and the linear shrinkage, shrinkage limit and free swell decrease after mixing the ISS into the red clay. In addition, spectrum tests show that after the red clay is treated by ISS, soil particles on the surface of the C elements had changed markedly, from scratch, confirmed the ISS elements combined with the role of soil particles.

Clay Treatment

Due to the insufficient understanding of the mechanism for soil strengthening by using Ionic Soil Stabilizer (ISS), the application of ISS in soil treatment is limited. In this paper, red clay samples were treated by using ISS and the effects were examined by the Atterberg test and uniaxial pressure test. In order to understand the mechanism, ISS dilution-based seepage test and ξ-potential test have been carried out. The results show that the ISS-Water mixture of 1 : 200 was the most effective ratio to reduce the plasticity index. The measurements indicate the thickness of the pair-electricity layer of adjacent clay layers and the repulsion force among soil particles is reduced, which in turn enhances the attraction force of the clay layers. This process strengthens the connection among the soil particles and thus increases the strength of the soil as detected by the experimental tests.

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.

In order to study the process of ionic soil stabilizer (ISS) reinforcing different kinds of soil, kaolin, red clay, landslide soil, expansive soil and quartz sand ,the five kinds of standard soil samples were treated by ISS of ratio 1:100. After 24-hour soaking and oscillation treatment, the supernatant was detected by laser-induced breakdown spectroscopy (LIBS). Comparing with the samples had not been treated by ISS, got the information of cation exchange. Experimental results showed that, the cation exchange in different soil was various, landslide soil exchanged more cation, and the cation exchange of kaolin and quartz sand was less. These studies will provide the experimental basis for ISS reinforcing mechanism research.
