Cold crushing strength – It is a measure of the mechanical strength of the refractory brick. In furnaces, cold crushing strength is of importance, because of bricks with high crushing strength is more resistant to impact from rods or during removal of slag than a brick with a low cold crushing strength.

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.

$\begingroup$ The issue with this kind of science-based questions: a calculation is required, which depends on the wall and the quality/strength of the wall. You may find calculations on line for a specific brick wall, not any brick wall. Without an accurate description of the wall involved, you can''t say anything science-based.
