Mechanical size reduction by using crusher and grinding mill is widely used in the aggregate producing industry and the mineral industry. In this study, physical, mechanical crushing and grinding properties of the rock specimens obtained from different bedrock were determined by using 8 different tests, to characterize the relationships between physico-mechanical properties of rocks and mechanical size reduction efficiency. The rock specimens were tested according to the procedures recommended by the ISRM (1981). ...

Salt weathering is a process of rock disintegration that takes place in a variety of environments and affects many kinds of rocks. Salt crystallization is one of the most important degradation mechanisms on the effect of rock weathering. Salt weathering is especially effect on the pores rock and affects the rocks, which contains cracks and micro cracks. In this study, the resistance of stones against salt weathering was estimated by ultrasonic measurements and weight loss approximation. Experiments were carried ac...
