An Experimental Study on the Evaluation of Unit-Water Content Acoording to Concrete Aggregate Variables through FDR Sensor

FDR 센서를 통한 콘크리트 골재 변수에 따른 단위수량 평가에 관한 실험적 연구

The unit quantity that affects the workability, shrinkage cracking, and durability of concrete is an important factor. Methods for measuring the unit quantity include a high frequency heating method, a capacitance method, a unit volume mass method, and a simple method. However, these methods have the disadvantage of poor measurement method, time required, and precision. To solve this problem, a relatively simple and fast measurement method was adopted to compensate for the shortcomings through a Frequency Domain Reflection (FDR) sensor, and the unit quantity was used. In addition, the measurement data was analyzed by deep learning to evaluate the unit quantity of concrete.
