RESISTANCE OF DOLOMITE AGGREGATES TO FREEZING AND ABRASIVE IMPACT STRAIN
Dolomite aggregates from quarries Čelina, Podsusedsko Dolje and Jarče polje were subjected to tests of abrasive impact strain and freezing.

| description | 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 (the paper is published in Croatian). |
