20.500.12556/RUL-124801 Laboratorijska analiza materialnih lastnosti mineralnih agregatov diplomska naloga Laboratory analysis of material properties of mineral aggregates graduation thesis Namen diplomske naloge je študija odpornosti naravnih agregatov iz različnih slovenskih nahajališč, ki se uporabljajo v gradbeništvu, proti drobljenju in obrabi. Izbrani agregati so drobljen apnenčast agregat, drobljen dolomitni agregat, savski prod in filitni skrilavec. V primeru filitnega skrilavca je izveden samo modificiran test odpornosti proti drobljenju. Po detajlnem študiju in opisu relevantnih standardnih testov, SIST EN 1097-1:2011 (Los Angeles) in SIST EN 1097-2:2020 (mikro Deval), sledi izvedba lastnih preiskav. Za vsak vir agregata smo preiskali tri vzporedne vzorce (paralelke). V nadaljevanju smo rezultate preiskav analizirali ter jih primerjali z rezultati preiskav drugih avtorjev. Ugotovili smo, da so lastnosti analiziranih rezultatov znotraj meja, ki jih za drobljen dolomit, drobljen apnenec in rečni prod navaja relevantna literatura. Za filitni skrilavec pa smo ugotovili, da je proti drobljenju slabo odporen. The purpose of the diploma thesis is to study the resistance of natural aggregates from various Slovenian deposits used in construction to fragmentation and wear. Selected aggregates are: crushed limestone aggregate, crushed dolomite aggregate, gravel from the river Sava and phyllite slate. In the case of phyllite slate, only a modified fragmentation resistance test is performed. After a detailed study and description of the relevant standard tests, SIST EN 1097-2:2020 (Los Angeles) and SIST EN 1097-1:2011 (micro-Deval), the implementation of our own investigations follows. Three parallel samples were examined for each aggregate source. In the following, we analysed the results of the investigations and compared them with the results of the investigations of other authors. We found, that the properties of the analysed aggregates are within the limits reported by the relevant literature for crushed dolomite, crushed limestone and river gravel. However, phyllite slate was found to be poorly resistant to fragmentation. agregat odpornost proti obrabi odpornost proti drobljenju Los Angeles mikro Deval modul oblike aggregate resistance to fragmentation resistance to wear Los Angeles micro-Deval shape index true true false [A.
