  • New Solutions To The Problem Of Making Measurements
  • Of Carbonation And Chloride Ingress
  • In Particular
  • In Concrete Structures Are Considered
  • The Approach Has Focused On The Design
  • Development
  • And Use Of Fiber-Optic Sensors (Foss)
  • Recognizing The Need In That Conventional Devices Are Often Either Inaccurate
  • Expensive
  • Or Unsuitable For Encapsulation In The Material
  • The Sensors Have Been Designed To Monitor
  • In Situ And Nondestructively
  • Relevant Physical
  • And Chemical Changes In Cementitious Materials
  • Three Different Types Of Fos Were Constructed
  • Tested
  • And Evaluated Specifically For This Application
  • These Being A Temperature Sensor (Based On The Fluorescence Decay) And Ph And Chloride Sensors
  • Based On Sol-Gel (Solidified Gel) Technology With Appropriate Impregnated Indicators
  • The Sensors Were All Designed To Be Inserted Into The Structures And Evaluated Under The Harshest Co

  • Being Mounted When The Mortar Is Poured And Thus Tested In Situ
  • With The Temperature And Phsensors Successfully Embedded In Mortar
  • The Outcomes Of These Tests Have Shown That Both The Temperature Sensor And The Ph Sensor Were Able
  • The Laboratory Tests On The Chloride Sensor Showed It Was Able To Make Measurements But Was Not Reve
