Two-phase system The soil is fluidified and homogenised in the downstroke phase by pumping of bentonite slurry into the soil. The mixing process can be supported by adding compressed air. The backflow of soil and bentonite can be pumped to a desanding plant where the sand is separated from the slurry which is then pumped back to the rig.

The addition of bentonite enhanced the OMCs and decreased the MDDs of the soil samples, according to the results of compaction tests on soil-bentonite mixtures (Fig. 5, Fig. 6, Fig. 7). Similar patterns were also observed in earlier investigations on the impact of bentonite on clay soil (Kumar and Yong, 2002a).
Construction and quality control for the SCB wall is more demanding than that needed for conventional soil-bentonite slurry walls. Backfill mixing, sampling and testing of this type of wall involve more exacting procedures. Recommendations are made herein for methods to carry out pre-job design mix testing and in-field quality control …
As mentioned earlier, for dry-blended bentonite, the mixing procedure in the laboratory is the same as with any cement or blended cement (described in the referenced document). For pre-hydrated bentonite, the bentonite has to be completely hydrated (30 min is required), as any solid additive, in mix water prior to adding cement.

to the strength of the soil, since the properties of grout and soil are so different. The cement-water ratio controls the strength of the grout. To decrease the strength of the grout, add more water. Drillers are accustomed to mixing water and bentonite first, but this will not allow you to control the water-cement ratio. Mix water and cement ...

Cutter Soil Mixing (CSM) is a specialized deep mixing technique that can be used in almost any soil type. The process incorporates cutter wheels, rotating about horizontal axes, and mounted on the end of a Kelly Bar, cutting their way into the soils to form a panel of improved soil that is rectangular in plan.
