“…The resistance to wear and fragmentation is largely influenced by the type of mineral aggregate used in tests and in practice. Generally, when selecting aggregates for different construction purposes, information on their geological and petrographic properties is one of the key aspects, as mechanical tests do not clearly describe any individual rock type [ 75 ]. Adomako et al [ 6 ] extensively analyzed the relationships between the geology and the resistance to wear and fragmentation.…”

“…According to García-González et al [ 2 ], the mechanical strength of aggregates is directly related to their mineralogy, porosity, and the metamorphosis degree of the source rock. In addition, Akseli and Leinonen [ 75 ] note that their tests of metavolcanic rocks suggest that the resistance to wear depends more on the mineralogical composition, while the resistance to fragmentation depends more on the changes of the texture.…”

“…Räisänen and Torppa [ 7 ], Sun et al [ 15 ], Rigopoulos et al [ 17 ], Akseli and Leinonen [ 75 ], Pang et al [ 78 ], and Räisänen [ 79 ] observe a high correlation between aggregate properties and their mineralogical, petrographic, and textural properties. Sun et al [ 15 ] conducted a pairwise correlation analysis and a multiple linear regression analysis in order to establish quantitative relationships between the mineral content and the morphological characteristics of aggregates.…”

“…Their results suggest that factor analysis contributes to a deeper understanding of how the strength properties of aggregates change in-service. Akseli and Leinonen [ 75 ] observe that although the mineral composition is generally a key parameter, textural features, especially the mineral fabric and grain-size distribution, occasionally prove even more important. Research performed by Ajalloeian and Kamani [ 80 ] indicates that an increase of the Texture Coefficient (TC) is accompanied by a decrease in the Los Angeles Abrasive (LAA) coefficient.…”

The aim of this article is to present the current knowledge and experiences related to wear and fragmentation resistance tests and to indicate those of their aspects that require further research. For this purpose, a review of the literature was performed. Results show that tests of resistance to wear (the MDE/DS test) and fragmentation (the LA test) are performed worldwide according to different standards (and thus following different test methods), which prevents a comparison of the obtained results. Comparative research into the MDE/DS and LA tests indicates that the MDE/DS test is more effective. The disadvantage of both tests lies in the dimension range of the aggregate. In addition, the use of steel balls in the LA test may not reflect the actual influence that the internal properties of the material have on the fragmentation process. A final review of the available knowledge allowed the formulation of proposals regarding further research directions, such as proposed changes of test methods, extensive analysis, and selection of optimal dimensions for tested aggregates, analysis of short-term and long-term tests, as well as extensive research into and an analysis of the impact of crushing on the physical, mechanical, and geometric properties of aggregates.

“…In the case of similar mineralogical composition, the effect of the rock texture is more significant than the mineralogy itself [5,6]. Akseli and Leinonen [7] emphasizes that the resistance to wear depends more on mineralogical composition, while the resistance to fragmentation depends more on the changes of the texture. The decrease in grain size of the minerals results in the increase of its specific surface, which leads to an increase of bond strength and hardness.…”

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.
