It is not properly designed and strength is not properly calculated.
This ensures near 20°C temperature around the clock, 365 days a year. 20°C is the ideal temperature for curing concrete. We record each compressive test in high definition for post analysis and client viewing if required. View our popup concrete cube crush demonstration video (2 min 14 sec). Test reports & video
Concrete cubes are typically made in moulds with dimensions of 150mm x 100mm x 150mm. The moulds have to meet the British Standard for testing hardened concrete (BS EN 12390-1:2000). When should the cubes be tested? Crush the cubes to test their strength – When each cube is ready for testing, it is put into a concrete crusher. This
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).
