2019-1-12 · 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.

Strength of Brick Masonry

The strength of a single brick masonry unit varies widely, depending on its ingredients and manu- facturing method. 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 ...

Mortar Compressive Strength

2019-5-4 · Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.
