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—, directional tension or simple compression—or shear (tangential), or allsided (, hydrostatic compression).

Physical Properties of Basalt Rock. Texture of Basalt Rocks. Rock Hardness. This property is usually measured to find out the compressive fracture strength, to denote whether a rock is softrock or hardrock. The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100300 Mpa ...

Basalt fiber is a relative newcomer to fiber reinforced polymers (FRPs) and structural composites. It has a similar chemical composition as glass fiber but has better strength characteristics, and unlike most glass fibers is highly resistant to alkaline, acidic and salt attack making it a good candidate for concrete, bridge and shoreline structures.

Broken stone is a widely used ballast in railways. It is obtained by crushing hard stones like granite, hard trap, quartzite etc. In lieu of broken stones, limestone and sandstone can also be used. It is suitable for highspeed railway tracks. The broken stone selected as ballast should be hard, tough and nonporous. It should stay strong against inclement weather conditions. Fig 2: .

Get PriceAfter processing, the crushed stone is subjected to sieving processes to obtain crushed stone in different sizes (Table 3). Extraction of crushed stone can be made from several rocks according to local geological characteristics such as: granite rocks, basaltic rocks (basalt and diabase), limestone (limestone and dolomite) and a small part of quartzite and gravel (Engidasew and Barbieri, 2014).
