    STRENGTH OF BRICK MASONRY tpub

    The compressive working strength of a brick wall or column laid with plain lime mortar normally ranges from 500 to 600 psi. For mortar to bond to brick properly, sufficient water must be present to completely hydrate the portland cement in the mortar. Bricks sometimes have high absorption rates, and, if not properly treated, can "suck" the water out of the mortar, preventing complete hydration
