Abstract:
Achieving the designed service life of a repair depends on several factors including the material selection. This month’s Q&A discusses using portland-limestone cement instead of specified portland cement to repair concrete severely damaged by freezing-and-thawing cycles and corrosion due to exposure to deicing salts. The repair is expected to last at least 30 years.
