Where to store before crushing of concrete cubes

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 a minimum 16 hours later to a maximum 72 hours, usually this done after 24 hours

    Apr 01, 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
