Non-destructive testing of concrete structures using GPR technique with an intermediate frequency antennas

Abstract EN

Ground penetrating radar (GPR) is a geophysical technique of imaging the subsurface structures at high resolution and it is a non-destructive technique ca consequently be applied in many civil engineering fields and sensitive environments.

The amount of data collected however can be very large and take a significant level of subjective experience to interpret.

This study focuses upon the ability of using the GPR with 250 MHz and 500 MHz antennas (intermediate frequencies) to investigate the reinforced concrete to indicate the quantity of steel bars and their configurations in the concrete constructed in the hidden mensurations.

The recent study shows the ability of using the intermediate frequency antennas for such fields.
