Temperature Measurement and Strength Estimation of Concrete by Using Rfid Tag With Temperature Sensor

Key Points

• The research aims to develop a method for estimating concrete strength based on temperature measurements during curing.
• Utilized RFID tags equipped with temperature sensors to continuously monitor concrete temperature for 91 days.
• Collected temperature data and actual compression strength for analysis.
• Estimated concrete strength using effective age and summative temperature methods.
• Concrete strength was accurately estimated using temperature data from the same environment.
• Estimations of strength for outdoor-exposed concrete showed promising accuracy under certain conditions.
