    • Compressive strength of rocks - PetroWiki

    2015-6-4  The high-porosity (33%) sandstone (Fig. 4a) has a low "crush" strength of about 55 MPa. With a lower porosity of 19%, Berea sandstone has a much higher strength of 440 MPa (Fig. 4b). Notice that in both Figs. 4a and 4b, permanent deformation remains even after the stress is released. This hysteresis demonstrates the damage to the matrix structure caused by exceeding the crush strength.

    2010-6-9  Semler [4] demonstrated that wollastonite based phosphate cements can have very high compressive strengths, in the order of 69 MPa (10,000 psi). However, that is when small sized samples are made. Making large samples with even partially neutralized H3PO4 is difcult because of excessive exothermic heat evolution during formation of these cements.
