Limestone is a sedimentary rock such as greater than 50% calcium carbonate ( calcite – CaCO3). There are many exceptional kinds of limestone formed thru a ramification of tactics. It may be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by using marine organisms including algae and coral (biochemical ...

Second, because crushed limestone has a lighter unit weight than gravel, it will require about 12% less crushed limestone than gravel to mix a cubic yard of concrete. Additionally, crushed limestone concrete is easier to saw through than gravel concrete. This is because most gravel is silica. Silica is almost impossible to cut with a steel saw.
