Abstract

Rad opisuje princip rada georadara kao nedestruktivne metode ispitivanja, područje upotrebe te način rada. Rad georadara se veže na ispitivanja za utvrđivanje dielektričnih svojstava, posebno dielektrične konstante kao jednog od najbitnijih svojstava materijala u električnim ili magnetskim karakteristikama materijala. U naglasak ovog rada stavljen je beton kao vodeći materijal u svijetu građevinarstva, zbog čega postoji potreba poznavanja i razumijevanja njegovih karakteristika, ali i kontrolu kvalitete u samim konstrukcijama. U radu su opisane četiri metode za određivanje dielektrične konstante i njihove prednosti i mane.

Abstract (english)

This thesis describes the operation of non-destructive ground penetrating radar, its area of applications and how it operates. It also describes the relationship between ground penetrating radar and the methods of determining the dielectric properties, especially the dielectric constant as one of the most important properties of electric and magnetic features. In this thesis, the focus is on concrete because it is the most commonly used material in construction today. For this reason, it is necessary to know and understand all its properties, but also for quality control of structures. In this thesis, four methods for measuring the dielectric constant are described.
