AbstractThis paper presents the results of concrete alkali-aggregate reaction damage investigations for two hydraulic structures using surface wave testing. The method uses a non-intrusive multi-sensor method to analyze the frequency-wave number of surface waves. The method allows solving Rayleigh surface wave propagation modes required for the determination of the shear wave velocity, from which the variation of Young's modulus with concrete depth can be estimated. The tests were conducted from the concrete surface only and the subsurface quality was mapped up to a depth of 1.50 m.
