Abstract
This paper validates the use of passive infrared thermography in size estimation of delaminations in external wall with various finishing materials and the influence of the cover depth of delaminations. Thermograms of a reinforced concrete wall surface with embedded delaminations in different depths were collected in 10-hr diurnal experiments and processed in an in-house program with a modified gradient algorithm. This paper reports the accuracy of the proposed size estimation method and how cover depth could affect the observed signals of delamination in thermograms in reflecting its actual size.
