CI-CMC (Contrivance Innovation - Clay Mixing Consolidation) is categorized to the Deep Soil Mixing (DSM) method that mixes cement slurry with soil in-situ and strengthens soft ground. Since DSM has a wide range of applicable soils with achievement of at will strength, it has been popular in the soil improvement market; however, it has been less cost effective in comparison with the other soil improvement methods with concept of soil compaction / densification, such as Stone Column, Dynamic Compaction.
Fudo has developed five (5) essential techniques and created CI-CMC by combining these techniques with DSM. They are:
- Forced driving / lifting device
- Open (window frame shaped) mixing blades
- Dual way mixing
- Two-nozzle ejection
- Atomized ejection system
By the combination of techniques above, CI-CMC achieves the creation of larger columns with less mixing time. This realizes the cost reduction without sacrificing the strength and the uniformity of columns. CI-CMC is the ideal Deep Soil Mixing method that copes with both economy and quality.
