    Oct 29, 2002 · In that paper there is a table of values for design. In the table the closest rock type to fractured basalt is just plain basalt with a working bond of 1.21-1.38 N/mm^2 and an ultimate bond of 3.86 N/mm^2. You might use a working bond of 1.2 N/mm^2 to determine the allowable capacity of a dowel grouted into the rock.

  • Compressive strength of rocks - petrowiki

    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.

  • compressive strengths of basalt - emaxlist

    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.

    The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100300 Mpa (Megapascal), its tensile strength: 1030 Mpa, and its shear strength: 2060 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong very strong category.
