· The compressive strength test is also known as the crushing strength test which is an important type of laboratory test conducted on bricks to determine the loadcarrying capacity of bricks when subjected to a compressive load. This test is performed utilizing a compression testing machine. 2. Apparatus Materials Required.
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. The compressive strength is then calculated ...
