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.

Based on the early strength many studies have been conducted to predict and analyze the compressive strength of concrete or cement mortar at 28 days or other days 1415 16 1718 the
