Early-age concrete strength monitoring using smart aggregate based on electromechanical impedance and machine learning
This paper presents a novel method for monitoring the strength development of early‑age concrete using embedded smart aggregates (SAs) that leverage electromechanical impedance (EMI) sensing combined with machine learning. The smart aggregates are embedded in the concrete mix during casting and continuously monitor conductance signatures, specifically the conductance resonant frequency (CRF) and conductance resonant peak […]
