Objective:

OS2.1, OS2.3, OS2.3

 

APPLICATION:

Site-batched, cast-in-place concrete that is not required to be reinforced and that is in contact with sulphate soil, which is deleterious to normal cement, that is used in:
  • footings, foundation walls, grade beams and piers,
  • crawl space ground cover,
  • basement floors, including floors of basement garages, subject to hydrostatic pressure or providing lateral resistance to foundation walls,
  • garage and carport floors, and
  • fireplaces and chimneys and footings for fireplaces and chimneys.
This applies to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

INTENT:

To limit the probability that an inadequate resistance to sulphate salts in the soil will lead to the inadequate performance or the premature failure of concrete under expected environmental or structural loads.
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.

    • 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,

Where concrete supports an environmental separator, to limit the probability that an inadequate resistance to sulfate salts in the soil will lead to the inadequate performance or premature failure of concrete under expected environmental or structural loads.
This is to limit the probability of:
  • the compromised integrity of the environmental separator, or
  • an inadequate resistance to air and moisture transfer through the concrete.
This is to limit the probability of:
  • pollutant ingress (from the exterior or from adjacent interior space, including soil gas, combustion products from parking garages, and particulates),
  • precipitation ingress,
  • condensation,
  • the ingress of moisture from the ground, or
  • the compromised thermal performance of components intended to provide resistance to heat transfer.
This is to limit the probability of:
  • the generation of pollutants from biological growth or from materials that become unstable on wetting,
  • deterioration, which could lead to further compromised integrity of environmental separators, or
  • an inadequate control of indoor air and surface temperatures, drafts, relative humidity, or water accumulation.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
