The paper deals with the continuous-time monitoring of mechanical degradation in concrete cubes under splitting. A series of experiments performed with integrated coda wave interferometry (CWI) and digital image correlation (DIC), supported with X-ray micro-computed tomography (micro-CT) is reported. DIC and micro-CT techniques were used to characterize the fracture process in detail. CWI method was proved to be effective in the assessment of damage level based on the changes in decorrelation between coda wave signals. The possibility of early detection of damage using CWI is promising for possible applications in the diagnostics of concrete elements.
