Abstract

The geological features and mechanical properties of metamorphosed volcanic and sedimentary rocks from a quarry in southern Finland were studied. Resistance to wear (from the studded lyres test and Los Angeles test) and petrography were used as quality indicators. The study reported was undertaken some 5 years after the opening of Pirkanmaa rock quarry in order to optimise the environmental and economic benefits. The study draws attention to the importance of the assessment of geologically heterogeneous rock quarries which makes it possible to produce a wider range of aggregates from the same quarry for various construction purposes, maximise the Crushing process and minimise changes in aggregate quality.
