Project description

Given the regular wintertime freeze-thaw cycling that occurs in Utah and the extensive exposure of concrete utility collars, concrete pavements, and bridge decks to deicing salt, Utah Department of Transportation (UDOT) has requested this new research on the durability of a rapid-setting calcium sulfoaluminate cement (CSAC). In particular, the objective of this research is to evaluate aspects of a typical CSAC mixture (CTS Rapid Set cement) that relate to freeze-thaw durability. The scope includes field sampling of previously placed CSAC, lab testing, and analysis.
