|Abstract:||The placement of conventional concrete in sub-freezing temperatures necessitates costly, labor-intensive measures to prevent freezing and ensure adequate early strength. An alternative method of sub-freezing concrete construction employs antifreeze admixtures which concurrently depress the freezing point and accelerate the hydration of fresh concrete. This concrete mixture has been applied successfully in cold regions where there are sub-freezing temperatures, ultimately enabling an extension of the construction season. In the last two decades, multiple field demonstrations of this technology have been implemented, many of which remain in service. The materials and mixtures used at these sites were evaluated in the short term with laboratory testing; however, most have not been inspected over time to evaluate their long-term durability in service. This document includes characteristics of durability, such as nondestructive and destructive testing measures to determine durability under long-term field conditions.|
