compressive strength of basalt rock. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
Mar 23, 2015 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.

Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as its compressive fracture strength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneousmetamorphic and sedimentary rocks
In general the compressive load from a dam on to its foundations will not exceed 10 MPa. The strength of a rock will depend upon its - Quality The degree of weathering Presence of micro-cracks The strength of a rock mass will depend upon - The number of cracks and joints The nature of their infilling material

It is de-
The strength of a rock mass will depend upon - The number of cracks and joints The nature of their infilling material Whether there are any rock-to-rock contacts across the joints Planarity and continuity of seams and foliations Table - Unconfined compressive strength of rocks
Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near surface environment of Venus.
Rock hardness property is usually measured to determine the compressive fracture strength, to determine whether a rock is a soft rock or a hard rock. T. The rock hardness of basalt is 6 as per the Mohs scale and can be observed through a combination of its compressive strength. Generally, 100-300 Mpa or Megapascal is the compressive strength.

Basalt and Trap. The structure of these stones is medium to fine grained and compact. Their color varies from dark gray to black. Fractures and joints are common in these stones. Their weight varies from 18 kNm3 to 29 kNm3. The compressive strength of these stones varies from 200 to 350 Nmm2. These are igneous rocks.
