concrete crushers test

Aug 29, 2018· As per IS456, the individual compressive value of a concrete cube should not be less than 75% from its grade. Example - If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%.

    Crushing Concrete Cube or Cylinder at 28 days

    Apr 01, 2018· The crushing of concrete cubes or cylinder samples is required in aconstruction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa.
