As the UK's largest independent construction materials testing laboratory, we understand that quality assurance is vital. SOCOTEC's wide scope of sampling and testing methods is based upon current British and European Standards and is accredited by UKAS to comply with ISO / IEC 17025, the competence standard for testing and calibration laboratories.

Variations in any/all of these criteria may affect the test results. The hardened concrete cubes are tested for compressive strength at 7, 28 and 56 days after casting by crushing, in accordance with BS EN 12390-3. Where required results can be emailed immediately, and test certificates are normally issued within 48 hours of completion.

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 achieved …

Compression Testing Machines. Typically concrete cubes are cured and tested in a manual or automatic concrete compression machine at 7 days and 28 days to assess compressive strength. ELE's comprehensive range of concrete compression machines is able to test concrete, mortar and cement samples such as cubes, cylinders, flagstones and beams.
