Abstract

The two most common used mechanical test in the aggregate industry for quality control are the resistance to wear (micro-Deval) and resistance to fragmentation (Los Angeles) tests. The quality of aggregates strongly depends on the textural, structural, and mineralogical features of the crushed material. These rock properties were experimentally studied on andesite samples from Tállya quarry. The mineralogical and chemical composition of samples were determined, textural observations were made on thin sections. The alteration was quantified using the chemical composition and mineralogical data. Micro-Deval and Los Angeles tests were conducted on the samples. The micro-Deval indices and the Los Angeles values showed similar trends, although the different type of stresses. The results showed that the examined mechanical properties of the Tállya andesites are complexly influenced by the textural and structural features, mineralogical composition, and alteration, however alteration has one of the most significant effects.
