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 […]

Why we can’t depend on maturity for concrete strength testing?

Maturity, or the temperature-time history of concrete, is a relatively common approach to estimate the compressive strength of concrete as a function of temperature and time. This technique takes the hydration process as a function, which means that as the temperature or curing time increases, then the hydration process accelerates and, as a result, the […]
