Resistance Of Concrete To Crushing
Properties of bricks
Jan 07, 2011 · The crushing resistance varies from about N/mm2 for soft facing bricks up to 140 N/mm2 for engineering bricks. The required thickness of an external brick wall is determined primarily by its ability to absorb rainwater to the extent that water does not penetrate to the inside face of the wall.
