The specimen should be weighed before the test. The specimen should be placed between the plate with proper alignment. Now, apply the load (kilonewton) gradually to the specimen. The specimen will break at maximum load (1 Division = 5 KN), which is noted down as the crushing value of the cube.
Compressive Strength Test The compressive strength test is performed on 15 cm × 15 cm × 15 cm cube, Metalic mould is used for casting concrete cubes. Fresh concrete is filled in three layers in a mould and each layer is compacted 25 times by tamping road, sometimes vibration table is used for compaction of the cube.
Any individual test result of a cube out of the above should not have value less than 21 N/mm 3. In case of doubt regarding the grade of concrete used either due to poor workmanship or based on results of cube strength test further tests should be conducted such as non-destructive test by Concrete Test Hammer, Ultrasonic Concrete Tester etc. Partial destructive test by drilling cores and
Compressive Strength of Concrete Cubes Lab Test & Procedure Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.
