2016-12-20 Limestone is a sedimentary rock composed largely of calcium carbonate (CaCO3). Millions of years before our era when surface area and volume of the ocean was larger, all kinds of shells and skeletons of marine life accumulated on the ocean floor and limestone was formed. Limestone is the most common rock all around the Mediterranean basin; it ...

2006-3-19 In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under ...

2021-5-7 Limestone is a sedimentary rock made of calcium carbonate (CaCO 3 ), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present. In many cases, the grains are microscopic ...
