                                                                  Wet soil mixing creates columns of pure grout with compressive strengths greater than concrete. - ProProfs

                                                                  Wet soil mixing creates columns of pure grout with compressive strengths greater than concrete.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Wet soil mixing creates columns that are a mixture of the existing soil and the introduced grout. Therefore the ultimate strength of the soilcrete will be controlled by the type of soil and the amount of grout introduced. Achievable compressive strengths are on the order of 200 psi for silts and clays; and in excess of 1000 psi for clean sands.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    "Wet" soil mixing actually refers to the property of the binder slurry being mixed into the soil. That is, "wet" refers to the grout, not the soil. Wet soil mixing is best suited for maximum moisture contents of about 60%.

    Rate this question:

  • 4. 

    What treatment geometries can wet soil mixing provide?

    • Single circular columns

    • Multiple column groups

    • Deep,long,linear homogeneous profile walls

    • Large shallow blocks

    • All the above

    Correct Answer
    A. All the above
    Explanation
          
        Single Axis Mixing            Mass Mixing Method          TRD - deep trench mixer

    The cost of wet soil mixing is generally _______ jet grouting.

    • More than

    • Less than

    • The same as

    Correct Answer
    A. Less than
    Explanation
    Wet soil mixing is roughly 1/3 the cost of jet grouting. Therefore it is beneficial to consider soil mixing first if project logistics permit and the desired results can be achieved.
