Abstract

Povećanjem potreba za nerazornim metodama ispitivanja povećava se uporaba georadara koji se osim u građevinarstvu koristi i u mnogim drugim granama znanosti. U građevinarstvu, ovaj se uređaj koristi za procjenu stanja armiranobetonskih konstrukcija.Georadar je uređaji koji na osnovu emitiranih i primljenih signala daje podatke o položaju objekta od koji se val reflektirao. U radu je pobliže opisan princip rada georadara i njegova primjena.Prikazan je utjecaj vlage i klorida u betonu te njihov utjecaj na rezultate ispitivanja georadarom. Predstavljeni su podaci provedenih ispitivanja iz dostupne literature.

Abstract (english)

As the need for non-destructive testing methods grows, so does the use of GPR also grows. GPR is not only used in construction but also in many other branches of science. In civil engineering, this device is used to assess the condition of reinforced concrete structures. GPR is a device that provides data about the position of the object from which the wave was reflected based on the transmitted and received signals. This thesis describes the operation of GPR and its application. It also, explains the influence of moisture and chloride in concrete and how these two elements affect the results of GPR tests. Finally, data from the tests performed are presented and can be found in the available literature.
