A Simple Guide to Concrete Cube Testing

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 sureThe 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 28Crushing Concrete Cube or Cylinder at 28 daysThe 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 from the mould to the cube before placing into a curing tank TheSimple guide to Concrete Cube Testing QEM Solutions
