CONCRETE STRENGTH MONITORING USING APPLICATIONS OF IOT
This paper explores the use of Internet of Things (IoT) technology for monitoring concrete strength during the curing process. By employing a thermocouple temperature sensor, the study tracks the temperature changes in concrete specimens caused by the hydration process, which is crucial for understanding the development of concrete strength over time. However, the paper highlights […]
A PCA-Based Approach for Very Early-Age Hydration Monitoring of Self-Compacting Concrete Using Embedded PZT Sensors
This paper investigates very early‑age hydration monitoring of self‑compacting concrete (SCC) containing fly ash replacement ratios (0%, 15%, 30%, 45%, 60%) using embedded piezoelectric (PZT) sensors and electromechanical impedance (EMI) signatures. The authors apply principal component analysis (PCA) to the EMI conductance signatures to extract indices that reflect the liquid to solid transition during hydration […]
Real-time monitoring of early-age compressive strength of concrete using an IoT-enabled monitoring system: an investigative study
This research develops an IoT‑enabled system by embedding temperature sensors within concrete for real‑time tracking of internal temperature‑time history, then using established maturity models (based on equivalent age and Arrhenius equation) to predict early‑age compressive strength. The sensor network uses long‑range wide‑area network (LoRa) communications and a cloud platform for data storage and visualization. The […]
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 […]
