چکیده مقاله:

Soil stabilization by admixture was developed in Japan during 1970s and 1980s. The treated soil hasgreater strength, reduced compressibility and lower hydraulic conductivity than the original soil. Theoriginal technique known internationally as the deep mixing method (DMM) was developedsimultaneously in Sweden and Japan in the mid-1970s. It is an in-situ soil treatment technology wherebythe soil is blended with cementitious and/or other materials. Grouting with chemical binder/s (sodiumsilicate, acrylamide, N-methylol acrylamide, polyurethane epoxy resins, amino-plasts, phenol-plasts, andlingo-sulfonates) is the effective method to improve the soil properties. The choice of a particular methodand chemical for soil stabilization will depend upon many factors like, soil type and layering, magnitudeof the load, situation and type of the project purpose, soil strength desired, toxicity and rheology.
