    Storage. The cubes should be covered with a damp cloth and a plastic sheet and stored in dry environment at a temperature range of 20 ± 5 degrees. The concrete cubes are removed from the moulds between 16 to 72 hours, usually this done after 24 hours. Make sure the cube ID is transferred to the cube from the mould before placing into a curing tank. The curing tank needs to operate at a temperature between 20 ± 2 degrees and provides a moist environment that allows the cubes

    Crushing Concrete Cube or Cylinder at 28 days

    01/04/2018· The crushing of concrete cubes or cylinder samples is required in a construction 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. The specified strength should be achieved at
