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 structural failure. 
This is to limit the probability of: 
- the space being unsuitable for its intended use, and 
- damage to the building.
