Salt retention in wetland soils and effects on dissolved organic carbon export
<p>Deicing salt runoff has negative effects on ecosystems. Wetland ecosystems can act as important filters for runoff pollution (e.g., nutrients), mitigating damage to plants and microbes. Wetlands are important sinks for nutrients and pollutants (e.g., road salt) and transformation spots for many …

Repair of damaged end regions of prestressed concrete girders using fiber reinforced polymer composite materials
… is the deterioration of the girder ends due to deicing salt exposure, thus reducing their shear strength. This thesis presents the results of the beginning stages of an Illinois Department of Transportation (IDOT) sponsored study to use FRP materials to repair and retrofit the damaged ends of …

The Development and Optimization of Raman Spectroscopy Analyses for Mobile Salinity Sensing
To quantify the amount of deicing salt on the roadway in near-real time, this thesis proposes a mobile salinity sensor using Raman spectroscopy. This thesis investigates the viability of using Raman spectroscopy to determine the concentration of salt deicer in an aqueous solution in near-real time …

Structural performance evaluation of the Postrite post-treatment corrosion inhibitor system
… in marine environments and areas of deicing salt usage. The chlorides penetrate the concrete and initiate corrosion of the reinforcing steel. A proven corrosion inhibitor system, the Postrite Post-treatment System, used in reinforced concrete rehabilitation, employs the use of a spray …

Mechanics and subcritical cracking of FRP-concrete interface
… interface. It has been found that water, deicing salt and alkaline solutions can substantially reduce the ERR at the crack tip needed to drive the subcritical crack growth along the epoxy-concrete interface. Once the small cracks grow to the critical length, critical debonding will occur, …

The Economy of Preventive Maintenance of Concrete Bridges Due to Corrosion
… or cold regions that require a large amount of deicing salt, carbon steel reinforced bridge decks have a short service life. Therefore, a well-planned preventive maintenance strategy needs to be implemented in order to postpone or eliminate the needs of major rehabilitation and replacement. In …

EFFECTS OF DEICING SALTS ON THE DURABILITY OF CONCRETE INCORPORATING SUPPLEMENTARY CEMENTITIOUS MATERIALS
… while exposed to solutions of one of the three deicing salts or deionized water in which the temperature of the specimens ranged from 39.2 ºF (4 ºC) during the wetting cycle to 73 ± 3 ºF (23 ± 2 ºC) during the drying cycle. Of special interest were the effects of CaCl2 and MgCl2, which result in …
