Are de-icers safe for concrete?

By François d'Entremont P. Eng.,

Canadian winters are harsh. As temperatures dip below freezing, ice can form on roads and walkways and make them hazardous. One method of keeping ice away is the use of de-icing agents, chemical compounds that melt ice and prevent more ice from forming. The oldest and most commonly used compound is salt. However, the use of salt needs to be controlled as it can sometimes be more hurtful than helpful.

This technical bulletin explores the issue of salt versus concrete. Although, it is important to keep
ice away from paths of travel for public safety reasons,  the de-icing agents used can have damaging, often irreversible effects on the integrity of the concrete infrastructure.
