Concrete test cube manufacturing and curing procedures,

Concrete test cube manufacturing and curing procedures. The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting). Early strength may also beA Simple Guide to Concrete Cube Testing,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 to hydrate properly.
