Method 3—Mixing of the soil-cement shall be accomplished in place. Mixing of the soil, cement (including fly ash), and water shall be accomplished by a single or multiple transverse shaft mixer, a traveling pugmill, or similar equip-ment approved by the engineer. A motor grader or similar equipment is not acceptable in lieu of the mixing equip-

Soil mixing is a process of mixing cement grout with soil in-situ (on site) to improve the strength of the soil and reduce its permeability. Soil mixing is used to construct impermeable earth-retaining structures and stable groundwater barriers, while improving the supportive properties of the soil.

Deep Soil Mixing. Deep Soil Mixing by the JAFEC Deep Mixing Method (DMM) is an advanced Ground Improvement method in which cement (or other agents) is mixed with in-situ soil to form-in-place soil-cement columns that increase the strength and reduce the compressibility of soft ground. The process produces a uniform soil-cement column with well ...

Soil-cement is made by thoroughly mixing soil, portland cement and water by one of the ways described in this article. The most practical soils are those that contain not more than 35 percent silt and clay and that are easily pulverized. If more than 4000 cubic yards are to be constructed, the central-plant mixing method proves easy and economical.

The Deep Mixing Method (DMM), also known in parts of the U.S. as soil mixing, is an in situ soil treatment and improvement technology mechanically blending the in situ soil with cementitious materials that are referred to as binders using a hollow stem auger and paddle arrangement. The intent of the soil mixing method is to achieve improved

Wet soil mixing is used in nearly any soil type, including organics. If the moisture content is greater than 60%, dry soil mixing may be more economical. The ease of mixing depends on the soil type, strength, water content, plasticity, stratigraphy, and texture. With wet soil mixing, treatment can reach depths up to 100 feet.
