Description

Damage caused by de-icing salts, known as salt-scaling, is a major contributor toward repair costs related to transportation infrastructure. Such damage consists of the removal of small chips or flakes of material at the exposed surfaces of concrete elements. To increase the service life of slabs on grade and reduce potential damage caused by salt-scaling, it is necessary to know the characteristics of salt-scaling and to understand parameters that could be used to control such damage. However, despite extensive studies, many details regarding salt-scaling are still not fully understood, and contradictions within the literature can be confusing. The aim of this presentation is to help better understand the salt-scaling phenomenon and provide insights into the effect of workmanship, mixture parameters, and concrete hardened properties on salt-scaling resistance of concrete.
