• Abstract:
  One of the most serious threats to Florida’s extensive coastal transportation infrastructure is the invasion of steel-reinforced concrete structures by chloride ions. In this project, University of Florida researchers investigated the use of a novel method of detection of chlorides in cement. Laser-induced breakdown spectroscopy (LIBS) uses a laser to transform the atoms and molecules in a sample of interest to a plasma, which emits characteristic patterns of light that can be interpreted to determine not only the constituents of the sample but also the amount of those constituents. The methods developed in this project promise to add another tool to the FDOT toolkit for inspection of concrete structures in coastal environments.
