Abstract
Za potrebe ovog rada, prikupljeni su uzorci litavca i litotamnijskog vapnenca iz napuštenog kamenoloma Bizek, koji su kroz povijest bili korišteni u izgradnji građevina i spomenika na području grada Zagreba. Uz to je prikupljen uzorak travertina tipa San Pietro Romano classico, dobiven od kamenoklesara, koji je odabran radi njegove uloge u restauraciji Zagrebačke katedrale. Ispitivanje litavca, litotamnijskog vapnenca i travertina na atmosferilije uključivalo je četiri vrste testiranja; ispitivanje otpornosti na djelovanje mraza, ispitivanje otpornosti na kristalizaciju soli, ispitivanje otpornosti upotrebom natrijevog sulfata i ispitivanje otpornosti na kisele kiše koje je rađeno po prilagođenom Slake durability test-u. Travertin je pokazao najbolje rezultate od sve tri vrste vapnenca, dok su se litotamijski vapnenac i litavac u većini ispitivanja pokazali nepostojani. Ispitivanja su provedena na Institutu građevinarstva Hrvatske (IGH) i prate službene norme za ispitivanje prirodnog kamena. Uspoređujući rezultate s relevantnom literaturom, proizašli zaključak je da ispitivanja arhitektonsko-građevnog kamena nisu dovoljno sveobuhvatna te da ne mogu uvijek precizno i dugoročno odrediti otpornost kamena na utjecaj atmosferilija.
Abstract (english)
For the purposes of this paper, samples of litavac and lithothamnium limestone were collected from the abandoned Bizek quarry, which was, throughout history, relevant for stone excavations used in the City of Zagreb. Travertine of the San Pietro Romano classico type was collected from a stone mason, and chosen due to its role in the restoration of the Zagreb Cathedral. The weathering testing of litavac, lithothamnium limestone and travertine included four types of tests; test of resistance to frost, test of resistance to salt crystallization, test of resistance using sodium sulfate and test of resistance to acid rains, which was done according to the adjusted Slake durability test. Travertine showed the best results out of all three types of limestone, while lithothamnium limestone and litavac proved to be unstable in most tests. The tests were carried out at the Croatian Institute of Civil Engineering (IGH), following the official standards for testing natural stone. Comparing the results with the relevant literature, the resulting conclusion is that the tests for architectural-building stone are not always comprehensive enough and that they cannot accurately determine long-term resistance of the stone to atmospheric conditions.
