Limestone can be split in any direction, and cut or carved into a broad array of shapes and sizes, sawn, planed, turned on a lathe or hand-worked into everything fromASTM Test Results Select Stone,Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.

The strength of a rock will depend upon its Quality The degree of weathering Presence of micro-cracks The strength of a rock mass will depend upon The number of cracks and joints The nature of their infilling materialLimestone vs. Sandstone Which Natural Paving Stone Is,Limestone . Vs. Sandstone . Limestone is calcite rock, and calcium compounds are actively reacting with strong acids. Thereby, users of Limestone pavers must take precautions against staining and avoid washing with acidic solutions at all. Sandstone is a siliceous rock, and silica/quartz is almost acid neutral in chemical reactions.
