고주파수분센서를 통한 고강도 콘크리트 단위수량 평가에 관한 실험적 연구

Abstract

In this study, unit-water content was measured using a frequency domain reflecometry(FDR) sensor that complements the problems of the existing unit-water content measurement method to evaluate the unit-water content affecting the workability, durability, and quality of high strength concrete. The experiment used the unit-water content of high strength concrete as a variable, and the accuracy and probability distribution of the unit-water content measured through deep learning were analyzed for the output value output through the FDR sensor. In the case of the unit-water content predicted by deep learning analysis, a high accuracy and high distribution of more than 93% were found within the error range of ±10 kg/m3 . In the future, research is needed to secure high reliability by utilizing data obtained through experiments with various variables.
