This letter demonstrates the potential for using diffuse ultrasound measurements to detect damage in concrete. Two different solutions diffusion equation, an infinite three-dimensional (3D) volume model that neglects geometric boundaries and a finite 3D cuboid model, are used required curve fitting procedure determine influence of on solution. The consider two types microcrack concrete, alkali-silica reaction thermal damage, show measured diffusivity parameter is related amount each specimen.
