Abstract: Severe deterioration of concrete joints has developed at a rapid rate for several Michigan highway projects. This deterioration was found to be linked to salt applications during the winter season. The driving force responsible for developing surface scaling can be explained by the cryogenic suction pump. For pure water on the surface the cryogenic suction pump is limited to internal capillary pore-suction, since external liquid is not available for ice-crystal growth as surface water freezes instantly. If a salt solution is present on the surface, the solution remains partially liquid during freezing (20 °C to -20 °C) which increases the liquid transport towards the freezing zone within surface pores. This was concluded from continuous length-change and temperature measurements during a freeze-thaw cycle.
