Experimental Study of Expansive Soil Improved by Ionic Soil Stabilizer

Abstract

Based on expansive soil of Anyang district of Henan improved by Ionic Soil Stabilizer, expansive soil is tested in the free swelling ratio test and Shrinkage test. The results show that after mixing the ISS into expansive soil, free swelling ratio of expansive soil decreases, and performance of expansive soil is significantly weakened. When the ISS with the water volume ratio of 1: 250, a free expansion to minimize the expansive soil. And the ISS than without after adding ISS, expansive soils line shrinkage and shrinkage limit significantly reduced, indicating that the weak soil particles adsorbed on the surface of the part of bound water has been replaced with off the coupling strength between soil particles to strengthen, soil shrinkage deformation smaller.
