The correction factor between standard and power measured Bond work index is 0.92 (limestone and crushed pebble) and 0.84 (bauxite). The difference between corrections can be explained by the homogeneous mineral composition of limestone (CaCO 3 content: 95%) and pebble (SiO 2 content: 86%) and the inhomogeneous composition of bauxite.

Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using an abrasive. Abrasion can be an undesirable effect of exposure to normal use or exposure to the elements.

Broch and Franklin (1972) proposed a testing method called the Point Load Test. The test consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. For these tests, rock pieces must have a length at least 1.4 times their diameter (Figure 2a). The point load index, Id, is equal to
