Abstract
A through transmission impact method for measuring the sound velocity in the concrete cubic samples, which are used for determination of the concrete durability, is proposed. It is shown that for elimination of the surface wave influence on the measurement accuracy of the compact cubic sample resonant frequency the impactor and the receiving transducer should be placed on the opposite sides of the cube. Besides in some cases must be used multichannel through transmission impact method.
