Useful Properties of Bricks. Compressive Strength; 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.

The compressive strength of a wall depends on the strength of the units used, the bricks or blocks, and the mortar. The assessment of the combined strength of the elements will also be affected by the degree of quality control exercised in manufacture and construction. The slenderness ratio, in turn, depends upon the effective height (or length) and the effective thickness of the wall or column.
