ASTM C666 – Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing


This test method covers the determination of the resistance of concrete specimens to rapidly repeated cycles of freezing and thawing in the laboratory by two different procedures:

  • Procedure A, Rapid Freezing and Thawing in Water
  • Procedure B, Rapid Freezing in Air and Thawing in Water.

Both procedures are intended for use in determining the effects of variations in the properties of concrete on the resistance of the concrete to the freezing-and-thawing cycles specified in the particular procedure.

Neither procedure is intended to provide a quantitative measure of the length of service that may be expected from a specific type of concrete.
