Standard Practice for Making and Curing Test Specimens for Evaluating Resistance of Coarse Aggregate to Freezing and Thawing in Air-Entrained Concrete

Importancia y uso:

4.1 This practice provides standard requirements for proportioning concrete, and for preparing and conditioning test specimens suitable for evaluating the durability of coarse aggregate in air-entrained concrete subjected to freezing and thawing in accordance with Test Method C666/C666M.

4.2 Concrete having an adequate air-void system may not be resistant to freezing and thawing if it contains coarse aggregate that becomes critically saturated. An aggregate particle is considered to be critically saturated if there is insufficient unfilled pore space to accommodate the expansion of water that accompanies the freezing.
