Evaluation of Half-Cell Corrosion Detection Test for Concrete Bridge Decks

摘要

The first chapter of the report discusses the corrosion of steel in concrete and provides information on the half-cell corrosion detection technique. In the second chapter, WSDOT's use of the test is reviewed, its concerns with the test are discussed, and the reliability of data collected is determined based on the field tests conducted. In the third chapter, a systematic procedure is developed with which to incorporate half-cell data into the WSDOT's bridge deck repair priority and protective system selection program. The findings of the work support the use of the half-cell test on bridge decks for classifying their overall condition.
