Abstract (croatian)
Dolomitni agregati iz kamenoloma Čelina, Podsusedsko Dolje i Jarče polje podvrgnuti su ispitivanju na udarno habajuća opterećenja i zamrzavanje. Pri tome su korištene nenormirane i normirane metode prema HRN-u i ASTM-u. Posebna pažnja posvećena je određivanju koeficijenta Los Angeles (KLA), koeficijenta drobivosti (KD) i indeksa pregranulacije (lp) prije te nakon 25 i 50 ciklusa zamrzavanja. Dobivene vrijednosti, prikazane tebelarno i grafički, posljedica su strukturno-teksturnih i petrografskih značajki, geneze i različitih postgenetskih procesa, prije svega tektonike (mikroraspucanost i kataklaziranje) i rekristalizacije. Posebno je utvrđen utjecaj veličine, oblika i međusobne povezanosti kristala dolomita na udarno habajuća opterećenja te defekata u obliku savijanja, tlačnih sraslačkih lamela i kalavosti.
Abstract (english)
Dolomite aggregates from quarries Čelina, Podsusedsko Dolje and Jarče polje were subjected to tests of abrasive impact strain and freezing. The tests were performed mainly according to standard HRN and ASTM methods and only partly were unstan-dardized methods used. Emphasis was placed on the determination of the Los Angeles coefficient (KLA), the crushing coefficient (KD), and the re-crushing indexes (lp), before and after 25 and 50 freezing cycles. The obtained data (presented both in tabular and graphic form) are a result of structural and textural petrograp-hic features, genesis and various postgenetic processes, markedly tectonics (microfracturing and cataclasis) and recrystallisation. The influence of size, shape and alignance of dolomite crystals to abrasion and impact strain was investigated together with curving defects, stress twining lamelle and cleavage.
