The abrasiveness of the rocks has a great influence in some of their applications, such as in the natural stone and in the civil engineering sectors. There are more than 15 test methods for its quantification. This work summarizes these methods and their classification into two large groups: in the case of natural stones the wear of the rock materials when in contact with a wear tool is taken into account; on the other hand, in civil engineering attention is paid to the wear that the rock causes in the cutting or drilling tools. In addition, those methods, in which the abrasiveness of rocks is defined according to the variation of the value of some of its properties, are also considered.
