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 the excessive deformation
of concrete, which could lead to:
- compromised structural integrity, or
- where concrete elements support 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 compromised structural integrity.
Where concrete elements support wood-frame floors, this
is to limit the probability of deflection or vibration of such floors,
which could lead to negative effects on the psychological well-being
of persons.
