Intent 1:
To limit the probability of:
- an excessive loss of water due to evaporation,
- the freezing of concrete before the initial set,
- slowed hydration of the concrete, or
- the freezing and expansion of the excess water not used
in hydration.
This is to limit the probability of:
- a failure to develop sufficient compressive strength
before building loads are applied,
- shrinkage and cracking, or
- the failure of internal bonds.
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 or step surfaces, which could
lead to persons tripping,
- the failure of supported handrails or guards, which
could lead to persons falling,
- the excessive deflection or vibration of supported wood-frame
floors, which could lead to persons losing their balance, tripping
or falling, and
- the 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.
