Thermal imaging measurements for assessing the structural integrity of a reinforced concrete water tower

Abstract

Reinforced concrete structures may exhibit degradation as they age. Thermal imaging captured using an infra-red camera can be used as a non-destructive and non-invasive technique to identify the structural health of such structures by providing a heat map which can be analysed through examination of the differences in temperature. A healthy concrete region generally exhibits a homogeneous temperature while degraded regions of the concrete tend to exhibit changes and variations in temperature.
