Test results for compressive strength obtained from the average of six broken pieces of specimens for each age. Aggregate mineral composition as per powder X-ray pattern (Fig. 2) is represented by carbonate, dolomite, and silica.
Jun 04, 2015· 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 .
The hardness of Dolomite is 3.5-4 whereas its compressive strength is 140.00 N/mm 2. Streak is the color of rock when it is crushed or powdered. The streak of Dolomite is white whereas its fracture is conchoidal. Luster of Dolomite is the interaction of light with the surface of Dolomite. Luster of Dolomite is vitreous and pearly.

Generally, sedimentary rocks can range from weak to medium (10-80 MPa), 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).
Mean tensile strength and compressive strength for selected sedimentary rock types (after Johnson and Degraff, 1988). The behavior of intact rock in the post-peak dom ain is not a true rock property and is partially dependent on the stiffness of the loading system. A testing machine consists of an assembly of
