Compressive strength of rocks

Estimating compressive strength General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0) Lithology is commonly derived during log analysis, so m may be estimated (Table 1) What is needed still is an initial measure of rock strength provided by C 0.

Properties of Slate

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 Slate is 3-4 whereas its compressive strength is 3000 N/mm 2 Streak is the color of rock when it is crushed or powdered.

Basalt Rock Properties and Uses

The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength: 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong - very strong category.
