9.3.1.9.(2)

Intent 1:

To limit the probability of:

• interruption of the hydration process,
• freezing and expansion of internal water, and
• over-watering due to the melting of ice.

This is to limit the probability of the failure of internal bonds in the concrete, which could lead to reduced compressive strength, which could lead to an inadequate resistance to:

• expected environmental or structural loads, or
• air and moisture transfer.

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.
