Laboratory tests performed on bricks
Compressive Strength of bricks is the load bearing capacity before it ruptures, when subjected to compressive stress. Hard and well burnt bricks have more compressive strength than the porous bricks. The crushing strength is the important factor for bricks, because it decides the suitability of brick for different uses. The crushing strength of brick can be find out with the help of crushing testing machine. Brick is fixed to the crushing testing machine and then compressive force is applied to the brick during testing operation. The crushing strength of brick should be minimum 105 kg/cm2.
