Bricks - Composition, Properties & Uses of Brick

    Sep 01, 2015 · The shearing strength of bricks is about one-tenth of the crushing strength. In practice, however, the bricks are not subjected to the tensile stresses. It may be noted that the strength of brickwork mainly depends on the type of mortar used and not so much on the individual strength of the bricks.
