The compression test measures concrete strength in the hardened state. Field concrete samples are prepared, cured and tested according to ASTM standard procedures. Specimens are prepared from concrete taken from different construction sites.
The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.
Test for compressive strength is carried out either on a cube or cylinder. Various standard codes recommend a concrete cylinder or concrete cube as the standard specimen for the test. American Society for Testing Materials ASTM C39/C39M provides Standard Test Method for
Designed to test 100mm, 150mm and 200mm cubes and cylinders up to 320mm long
Fully compliant with BS EN 12390-4 in terms of Force measurement &the stringent stability, alignment & restraint requirements of the Load Frame.
- Compact Welded steel load frame with a high degree of mechanical stability
- Ball-seated upper platen
- Lower platen, positively located on the loading ram, marked to allow centring of both cubes and cylinders
- Loading ram with cover to prevent debris damaging it during testing and a limit switch to prevent it from exceeding the maximum limit of travel
- Frame fitted with mesh guards at front and rear to protect the operator
- Front guard is hinged for ease of access
- Supplied with 300mm diameter upper and lower platens and 200mm diameter distance pieces to allow for testing cubes and cylinders
