9.20.3.2.(6)

Intent 1:

To limit the probability of inadequate compressive or bond strength, which could lead to:

• cracking of mortar joints and grout,
• inadequate bonding of mortar with masonry units, or
• inadequate bonding of grout with masonry units and reinforcing steel.

Where masonry construction is required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
