concrete compressive strength test

1.       Size of concrete specimens for compression strength test  

Concrete cubic specimen: 150X150X150mm, 100X100X100mm, 200X200X200mm

Cylindrical concrete specimen: φ150X300mm, φ100X200mm, φ200X400mm

2.       Brief introduction of concrete compressive strength test procedure

1)       Placing  the concrete specimen---place the test specimen on the lower bearing  block. Carefully align the axis of the specimen with the center of  thrust of the spherically seated block.

2)       Apply  the load continuously and without shock until the specimen fails and  record the maximum load carried by the concrete specimen during the  test. Note the type of failure and the appearance of the concrete.
