• Abstract:
  This report describes an evaluation performed by the California Department of Transportation (Department) of the
  
  ECI-1 Embedded Corrosion Instrument, developed by Virginia Technologies, Incorporated (VTI).
  
  The ECI-1 Embedded Corrosion Instrument was designed to several parameters related to corrosion of
  
  reinforcement in concrete. These parameters include chloride ion sensing, concrete resistivity, linear polarization
  
  resistance (LPR), corrosion potential, and concrete temperature. These measurements can allow corrosion
  
  engineers to monitor corrosion activity within reinforced concrete in a non-destructive manner.
  
  Four ECI-1 devices were evaluated in laboratory experiments in mortar samples. Chlorides were introduced using
  
  an external power supply to accelerate the ingress of chlorides from ponding solution into the mortar matrix.
  
  Corrosion parameters were obtained using the ECI-1 devices and an external potentiostat for comparison. The
  
  results of the laboratory evaluation are presented in this report.
  
  In addition to the laboratory study, four ECI-1 devices were installed in a bridge deck located in Northern
  
  California. The bridge deck is subjected to deicing salt applications during winter snow periods and will be used
  
  to evaluate the long-term (10 to 12-years) performance of the ECI-1 devices. The installation procedures and
  
  preliminary data for these devices are presented in this report.
