Deep Mixing Method - an overview ScienceDirect Topics

Deep mixing method. The deep mixing method (DMM) is a kind of deep in situ admixture stabilization using hardening agents such as lime, cement, or a combination of materials. The improvement becomes possible by ion exchange at the surface of clay minerals, bonding of soil particles, and/or filling of void spaces by chemical reaction products.

DEEP SOIL MIXING FOR GROUND IMPROVEMENT -

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.
