    Rock properties and their importance to and igneous rocks range from medium to very strong (40-320 MPa). The highest unconfined compressive strength observed in a rock is on the order of 400 MPa (e.g. nephritic jade). Egyptian quarries are littered with spherical diabase pounders (Klemm & Klemm 1993), examples of which can be

    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. C 0 can be estimated from porosity or sonic velocities, but many

    strength is the most commonly measured strength parameter and this is also true of rock specimens. For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load

  • The effect of water on the compressive strength of diabase

    The compressive strength of water soaked diabase is found to be about 60% of that of diabase dried at temperatures greater than 190°C. Several solvents other than water failed to cause a decrease in the strength of diabase. This suggests that water is involved in a chemical reaction during the fracturing process, and that its effect is not simply capillary action. <P />

  • Diabase (Dolerite)

    The reason why diabase was used for pounders by the ancient Egyptians was due to its very high fracture strength. As presented in Table 2 of the section on Rock Properties a typical diabase has an unconfined compressive strength that can be considerably higher than that of a typical granite or other coarse-grained igneous rock.
