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.
This is to limit the probability of:
- compromised structural integrity of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration, or
- in assemblies exposed to moisture or the exterior, damage
and deterioration.
For floors and elements supporting floors, this is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
persons.
