9.3.1.4.(1)

Intent 1:

To limit the probability that the use of inappropriate aggregate materials or the presence of an excessive proportion of contaminants in aggregates will lead to 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.
