Abstract
In the research three NDT methods: indirect Ultrasonic Pulse Velocity, Impact-Echo (IE) and Ground Penetrating Radar (GPR) were used for investigation of concrete slabs with well-defined reinforcement and artificial defects. The obtained results shows the big potential of combination of UPE, IE and GPR methods for detection of wide range of defects in concrete structures. These methods were implemented for UIR scanner development – NDT system which accelerate assessment of concrete structure. Moreover, when the result of one method is not clear and individually the method seems to be not effective, the data from the other one allows for proper interpretation of concrete integrity.
