9.3.1.8.(1)

Intent 1:

To limit the probability that substandard admixtures will be used, which could lead to:

• the spalling or premature deterioration of concrete, or
• the inadequate performance or premature failure of concrete under expected environmental or structural loads.

Where concrete supports or is used in chimneys or fireplaces, this is to limit the probability of the compromised integrity of the chimney or fireplace, which could lead to the ignition of combustible building components.

This is to limit the probability of harm to persons.
