Abstract

Parking structures are among the most challenging types of structures to design in terms of durability, especially in colder climates, where deicing salts are used. Chloride ions contained in deicing salts can quickly deteriorate concrete and may cause concrete slabs to reach a critical condition less than 10 years after being constructed if they are not protected adequately. This article provides guidance on how to protect hollow-core slabs from premature deterioration in parking applications to improve the life span of the structure.
