DEEP SOIL MIXING FOR GROUND IMPROVEMENT CivilDigital

Nov 15, 2017  DEEP SOIL MIXING. The properties of soft cohesive soils can be improved by mixing of a variety of chemical additives. The addition of lime, fly ash and cement in different combinations can significantly improve the shear strength and compression properties of such soils. Other additives can be used to fix pollutants in place to prevent leaching or to reduce soil permeability.
