Jul 17, 2017 · Brick and block are both relatively strong materials, but their strength in a wall is affected by the type and quality of mortar holding them together. According to the Masonry Advisory Council, all concrete blocks must have a minimum compressive strength of 1900 pounds per square inch. Many dense blocks are stronger than this.
What is Compressive strength of brick masonry? A wall or column carrying a compressive load behaves like any other strut, and its load bearing capacity depends on the compressive strength of the materials, the cross-sectional area and the geometrical properties as expressed by the slenderness ratio .
A mortar that is stronger in compressive strength than the masonry units will not "give," thus causing stresses to be relieved through the masonry units—resulting in permanent damage to the masonry, such as cracking and spalling, that cannot be repaired easily.
coordinating dimensions of a brick is 10mm (0.5“)and this difference is taken up with the layer of mortar into which the bricks are pressed when laying. The working dimensions are also known as the nominal size of a brick.
Brick can have an ultimate compressive strength as low as 1,600 psi. On the other hand, some well-burned brick has compressive strength exceeding 15,000 psi. Because portland-cement-lime mortar is normally stronger than the brick, brick masonry laid with this mortar is stronger than an individual brick unit.
