Summary: In this study, an AC-based electro-mechanical impedance (EMI) technique was utilized to evaluate the performance of smart cementitious composite-based impedance sensor (SCC-iS) over a frequency range, and then it was employed as an embeddable sensor for real-time monitoring of damage in concrete structures. Experimental results showed that 0.50 wt% CNT concentration is the optimum for developing efficient SCC-iS. Under compressive loading, the electrical variation in impedance (EVZ) and electrical variation in conductance (EVC) in SCC-iS demonstrate correlation with compressive strain and can detect damage effectively.

Summary: Asset managers globally are facing challenges in managing aged infrastructure in reinforced concrete. Early detection of reinforcement corrosion is crucial for targeted maintenance and repair, with the acoustic emission technique showing promise in achieving this goal. The research in this article investigates the characterisation of different damage sources during corrosion in reinforced concrete, utilizing small-scale reinforced concrete prisms and accelerating conditions in a laboratory setting. Signals from various acoustic emission sources are analyzed in both the time and frequency domain, with the wavelet transform providing insights into time-frequency characteristics. The results highlight the importance of validating acoustic emission signals with crack measurements, with the shift in peak and center frequency proving to be a valuable indicator.
