The crushability index test is an experimental method that determines the resistance indirectly measured by the force exerted on the rock crusher against the fracture. Crushed rocks are sieved through a 9.52-mm mesh and the percentage of passing material is described as the crushability index (CI) (Kahraman and Toraman 2008 ; Toraman et al. 2010 ).
