Intent 1:
To limit the probability of:
- an inappropriate cement/aggregate ratio, or
- excessive water in concrete.
This is to limit the probability of:
- aggregate segregation,
- reduced compressive strength,
- increased shrinkage and cracking, or
- low resistance to air and moisture transfer for foundation
walls and basement floors, de-icing salts, water absorption or freeze-thaw
stresses.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- where concrete supports or is used in an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to the deterioration of building elements,
which could lead to further compromised structural integrity, or
- where concrete supports walls or floors, 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,
- compromised operation of windows and doors, and
- damage to the building.
