Properties of Bricks – Compressive Strength -Hardness ...

Jan 12, 2019· Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.
