Intent

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, or
  • 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.

This is to limit the probability of harm to persons.
