Intent 1:
To limit the probability of:
- an inappropriate cement/aggregate ratio, or
- excessive water in concrete.
This is to limit the probability of:
- aggregate segregation,
- reduced compressive strength,
- increased shrinkage and cracking, or
- low resistance to air and moisture transfer, deicing
salts, water absorption or freeze-thaw stresses.
This is to limit the probability of compromised structural
integrity, which could lead to:
- 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.
This is to limit the probability of harm to persons.
