· · For low shear stresses, crushing is limited to angularities and crumbling in the form of flaking at the grain contact zones. The crushing of the grains increases with increasing shear stresses, but it is difficult to indie at what value of the first breaks appear. Statistical modeling. The results obtained show a dispersion of the crushing resistance values .
the loading, hauling, and crushing costs. The size distribution analysis of the rock fragmentation by sieving is a direct and accurate method but it is very time consuming and costly. Fragmentation analysis by digital image processing is a low cost and quick method. Split system is one of the digital image processing software developed to compute the size distribution of fragmented .

· Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
· At the global level, natural stone producers deal in the selling of a variety of natural stones, including granite, marble, quartzite, limestone, and sandstone. The best benefit of using these stones for the construction purpose is that they are strong and make any space look beautiful. All stones don't have the same strength that makes them longlasting. The Mohs .
