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.
