A simple non invasive technique for structural health monitoring

The efficiency of a parallel plate capacitor for the detection of moisture concentration in concrete structure is proposed in this paper. As the presence of moisture in the concrete structure deteriorate the health of the structure, therefore its presence should be correctly examined. In this paper, the effect of moisture on the electrical properties such as impedance, capacitance, phase angle, dissipation factor of concrete is thoroughly studied. A fly ash brick has been taken in order to analyze the performance of the proposed methodology.
