INTENT:

To limit the probability of:
  • an excessive loss of water due to evaporation,

  • 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, which could lead to:
  • structural failure, or
