Hollow Brick Masonry

The compressive strength of hollow brick masonry depends on unit strength, mortar type, mortar bedding area, grouting and thicknesses of face shells and webs. The design strength of the masonry can be determined by testing sample prisms (prism test method). During construction, strength can be verified using prism testing or from tabulated ...


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.
