An Experimental Study on the Prediction of Concrete Compressive Strength by the Maturity Method Using Embedded Wireless Temperature and Humidity Sensor

콘크리트 매립형 무선 온습도 센서 기반 적산온도법을 이용한 콘크리트 압축강도 예측에 관한 실험적 연구

Prediction of compressive strength of concrete by Maturity Method is applied in construction site. However, due to the use of wired type high-priced equipment, economic efficiency and workability are falling. In this study, a newly developed concrete embedded wireless sensor is used to perform a mock-up test. Next, the concrete compressive strength of the Maturity Method is predicted using Saul and Plowman's function as measured temperature data. The predicted concrete strength at the beginning of the age was the actual strength and stiffness, but the error rate was less than 1% at 28th day.
