An Experimental Study on the Accuracy of Concrete Unit-Water Content Using High-frequency Water Fraction Sensors

고주파수분센서를 이용한 콘크리트 단위수량 평가 정확도에 관한 실험적 연구

The unit quantity is an important factor influencing the durability, workability, and quality of concrete. Methods for measuring the unit quantity include a high frequency heating method, a unit volume mass method, a capacitance method, and a microwave method. However, these methods have disadvantages of poor measurement method, time required, and accuracy, and a relatively experimental method compensating for these disadvantages was used to measure the unit quantity using a high frequency main sensor (FDR) capable of simple and fast measurement. In addition, the unit quantity was evaluated by analyzing the measurement data through deep learning.
