Crushing Concrete Cube or Cylinder at 28 days
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

Testing hardened concrete
A hydraulic press applies load to a concrete test cylinder to measure compressive strength. The machine records the load required to crush the cylinder. Factors that can affect test results include the type of machine used and the rate at which it applies the load, capping, cylinder placement in the machine, and mois-ture conditions.
