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 […]

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 […]
