Abstract

U ovom radu opisana je provedba kontrole kvalitete laboratorijskih ispitivanja posmične
čvrstoće tla, te su usporedno prikazani rezultati svih ispitivanja koja su provedena na
uzorku gline, sukladno zahtjevima normi. Pokusi provedeni u akreditiranom laboratoriju
tvrtke Geotehnički studio d.o.o. i laboratoriju Rudarsko-geološko-naftnog fakulteta u
Zagrebu. Kontrola kvalitete rezultata analizirana je s polazišta ponovljivosti i
obnovljivosti, te međulaboratorijske usporedbe. Ispitivanja su provedena na uzorku
modelarske gline za komercijalnu upotrebu. Osim provedbe ispitivanja izravnog posmika,
provedena su još i sljedeća ispitivanja: određivanje vlažnosti, određivanje zapreminske
težine, određivanje gustoće čvrstih čestica, određivanje Atterbergovih granica te
određivanje granulometrijskog sastava tla metodom areometriranja. Rezultati ispitivanja
dobiveni u ova dva laboratorija međusobno su uspoređeni i analizirani, te pokazuju da su
odstupanja u dopuštenim granicama prema normi.

Abstract (english)

The implementation of quality control results was described in this thesis, and the results
of all tests carried out on the clay sample were parallely shown, in accordance with the
standard requirements in the accredited laboratory at Geotehnički studio d.o.o., and at the
laboratory of Faculty of Mining, Geology and Petroleum Engineering in Zagreb. The
quality of results was analyzed from the point of repeatability and reproducibility, and
interlaboratory comparison. The tests were done on the clay sample for commercial use.
Besides direct shear test, the following tests were also carried out: determination of water
content, calculation of unit weight, determination of the specific density of solid particles,
Atterberg limits and hydrometer test. The test results from both laboratories were
compared analysed, and they have shown that the deviatons are within acceptable limits,
according to the standards.
