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, 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,
which could lead to compromised structural integrity.
This is to limit the probability of:
- uneven concrete floor surfaces, which could lead to
tripping,
- excessive deflection or vibration of supported wood-frame
floors, which could lead to a loss of balance, tripping or falling,
and
- failure of fireplaces or chimneys, which could lead
to the leakage of combustion products, including carbon monoxide gas,
into living space, which could lead to the asphyxiation or acute poisoning
of persons.
This is to limit the probability of harm to persons.
