Physical Properties of Scoria
Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Scoria like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Scoria rock are vital in determining its Scoria Texture and Scoria Uses.
Hardness and Strength of Scoria
The physical properties of Scoria depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Scoria is 5-6 whereas its compressive strength is 70.00 N/mm2. Streak is the color of rock when it is crushed or powdered. The streak of Scoria is white whereas its fracture is conchoidal. Luster of Scoria is the interaction of light with the surface of Scoria. Luster of Scoria is subvitreous to dull. Scoria cleavage is perfect. The specific gravity of Scoria is . Scoria is opaque in nature whereas its toughness is 2.1.
