Abstract:
Can a total air content of 4% provide comparable freezing-and-thawing durability as a total air content of 6%? Based on the literature discussed in the Q&A, the effectiveness of air voids in concrete in providing durability depends on characteristics of the air-void system, including the average air-void size and the spacing of the voids.
