Characteristics of Dunite
Many rocks have distinct characteristics. Some of the Properties of Dunite are hardness, structure, streak, fracture etc. Dunite is significant as it is composed of minerals and has variety of uses in our day to day life. The characteristics of Dunite plays an important role in its identification.
The hardness of Dunite is 3.5-4 on Moh’s hardness scale. Rocks according to their hardness are divided into:Hard Rocks, Soft Rocks and Rocks with Medium Hardness.
Fracture of Dunite rock is irregular. Its specific heat capacity is 1.25 kJ/Kg K. Dunite is heat resistant, pressure resistant, wear resistant. Some of its uses are:
- Interior Uses: Decorative aggregates and Interior decoration.
- Construction Industry: As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
