(a) Rock material properties Rock material properties that are essential in assessing hydraulic erodibility of rock include rock type, color, particle size, texture, hardness, and strength. Seismic velocity, weathering, and secondary cavities are prop-erties related to both the rock material and mass. Rock material properties can be described different rock types would have different material properties and behaviour. (Edy Tonnizam et al., 2005) For example, granitic rocks differ from shales or schists. • Limestone is yet another type of rock with its unique solution properties. Owing to the different nature and origin of the rock types 2.4.5 Material-handling properties2.4.5.1 Abrasion properties. The Bond abrasion index (Ai) is used as a measure of the relative abrasivity of different rock materials on metal and is important to understand for process plant design and operation in crushing, screening, and especially grinding (Bond, 1963). May 31, 2016 In the nature there are so many types of rocks are available which are used in construction and engineering purposes. But when it comes to usage all of them having different properties and parameters. Mainly for engineering purposes rocks need to be classified. In 1974 Z.T.Bieniawski proposed the Geomechanics classification system of rocks based on [] Rock Rock Mechanical properties: When a stress σ (force per unit area) is applied to a material such as rock, the material experiences a change in dimension, volume, or shape. This change, or deformation, is called strain (ε). Stresses can be axial—e.g., directional tension or simple compression—or shear (tangential), or all-sided (e.g., hydrostatic compression).
