    Soil cement Wikipedia

    Soil cement is a construction material, a mix of pulverized natural soil with small amount of portland cement and water, usually processed in a tumble, compacted to high density. Hard, semi-rigid durable material is formed by hydration of the cement particles. Soil cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a subbase layer reinforcing and protecting the subgrade. It has good compressive and she

    REINFORCEMENT OF SOFT SOILS BY SOIL MIXING

    Soil-cement columns are used to reduce the potential total settlement of soft soils under service loads. The total time required to complete reduced settlement will be less. However, the rate of settlement of a composite material usually remains similar to the original soil because soil-cement columns have a permeability about the same as for the in-situ soil. Soil-cement columns form a

    The “FS Soil-cement Column” system is particularly suited for the very poor and water saturated soil formations found in the coastal areas of the Philippines, where the soil in general is characterized by very low bearing capacity and low shear values. The overlaying soil strata of this formation have an extremely high liquefaction potential in earthquake condition.
