Device and method for detection of alkali-silica reactivity on concrete structures

Abstract

Embodiments of the disclosure include a remote inspection system for detecting and assessing the alkali-silica reaction (ASR) in situ in concrete, the system including an image acquisition device capable of excluding ambient light from a concrete surface and being placed against and imaging the concrete surface, the image acquisition device comprising a mirrorless camera and daylight and short-range UV light sources wherein the light sources and mirrorless camera are capable of being controlled remotely. Aspects of the present disclosure includes a method of inspecting in situ the level of ASR present in concrete, including placing an image acquisition device as described above. In yet another aspects, the method further includes acquiring at least one image of said concrete surface prior to treatment with uranyl acetate to assess natural fluorescence in the concrete and acquiring at least one image of said concrete surface after treatment with uranyl acetate.
