Intent 1:
To limit the probability that concrete block of
inadequate compressive strength will be used, which could lead to:
- an inadequate resistance to water absorption, which
could lead to excessive water absorption, which could lead to blocks
cracking due to freeze-thaw stresses, or
- an inability to support loads, which could lead to blocks
cracking.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- where elements support or are part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
or
- an inability to resist expected loads, which could lead
to
- the excessive deformation or deflection of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use, or
- damage to the building.
