Abstract:
For many years, Infrared Thermal Imagery, or Infrared Thermography, has been used as an nondestructive testing method to locate thermal problems in buildings, to track roof leaks, and to detect delaminations in reinforced concrete bridge decks. For the last 3 years, the authors have been exploring thermal imagery applications to fresh and to recently cast concrete. While comprehensive studies have been performed under indoor and outdoor laboratory conditions, the authors recently monitored concrete batching facilities and a construction site with an infrared scanner. This brief article introduces some of the field observations made and examines further the opportunities and challenges available from exploiting thermal imaging.
