Compressive /Crushing strength of bricks (Indian Made) are very variable, and may vary from30 kg/sq.cm to 150 kg/sq. cm for hand-made burnt bricks, while Crushing strength of heavy duty bricks machine pressed (also called engineering bricks) may have compressive strength as high as 450 kg/sq. cm, and even 500 kg/sq. cm.
[email protected]The procedure for the crushing strength test on bricks involves the following series of steps: 1. The specimen with the mortar filled face upwards is placed in the plates of the compression testing machine. 2. The load is then applied axially at a uniform rate of 14N/ mm² per minute until failure occurs. The maximum load at failure is recorded. 3.
