Abstract

U ovom diplomskom radu pisati će se o čvrstoći stijena, točnije vlačnoj čvrstoći. Obraditi će se teorijski i praktični dio u kojem će se izvršiti ispitivanje direktne i indirektne vlačne čvrstoće (brazilski test) na dva različita uređaja, te će se na kraju usporediti rezultati. Uzorak koji će se ispitivati je Portugalski vapnenac, čije će se karakteristike detaljnije opisati u tekstu.
Cilj ovog diplomskog rada je vidjeti koje su razlike ili sličnosti u rezultatima ispitivanja na ta dva uređaja, da li je ispitivanje brazilskim testom pouzdano, te da li se direktno ispitivanje može zamijeniti indirektnim, zbog jednostavnosti u izvođenju. Ispitivanja su provedena u geomehaničkom laboratoriju tehničkog fakulteta u Lisabonu (Instituto Superiore Tecnico), pod vodstvom profesorice Matilde Costa e Silva, te uz pomoć laboratorijskog tehničara.

Abstract (english)

Abstract: This master thesis is devoted to rock strength, more precisely tensile rock strength testing.
Thesis is consisted of the theoretical part and the practical part during which direct and indirect (Brazilian test) tensile rock strength testing was done on two different machines. Comparison of the test results is presented at the end of the report. Sample on which the testing was done is Portuguese limestone, characteristics of which are described in the report. Purpose of this master thesis is to present differences and similarities of direct and indirect testing methods, and to make conclusions about the reliability of the indirect method and replaceability of direct testing with indirect testing. Advantages what would be gained from this replacement are related to the simpler procedure of indirect testing. Testing was done in geomechanic laboratory in technical faculty Instituto Superiore Tecnico in Lisbon, mentored by professor Matilde Costa e Silva, and laboratory technician.
