A recent study has shown that, with proper post-processing of the data, hyperspectral imaging can automatically and reliably detect weak from strong hardened concrete and normally fired bricks, all without any destructive testing or direct contact with the materials. This technology will help civil engineers and developers rapidly analyse the integrity of construction materials and assist with the documentation, preservation and restoration of historical structures, as well as the asset management of infrastructure.
Professor Debra Laefer from NYU’s Center for Urban Science and Progress (CUSP), in collaboration with Professor Aoife Gowen and Zohreh Zahiri from the University College Dublin, recently demonstrated for the first time the ability to use hyperspectral imaging to characterise differing strengths within a single type of construction material. The concrete results were just published in ScienceDirect and the brick ones in Research Gate
