Theoretical Analyses and Experimental Research on a Cement Concrete Dielectric Model
Publication: Journal of Materials in Civil Engineering
Volume 25, Issue 12
Abstract
The establishment of a cement concrete dielectric constant model is the basic and key technique for applying the electromagnetic wave technology to concrete structure quality testing and internal damage detection. Based on the characteristics of the cement concrete, a new dielectric constant model is developed in theory after the linear model, the root-mean square model, and Rayleigh model are analyzed comprehensively. Dielectric constants of cement concrete are measured using hardware to evaluate components and circuits for frequency ranges. The theoretical analyses and experimental studies show the proposed model precision is highest and most suitable to interpret cement concrete dielectric properties when compared with the other three models.
