Sentence 9.3.1.3.(1)

Intent 1:

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 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.
