Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells.

· Introduction Crushed limestone is increasingly being used as coarse aggregate for concrete. Unlike normal aggregates with a high composition of silica (SiO 2), limestone aggregate consists mainly of the mineral calcium carbonate (CaCO 3) that plays a significant role in the differences in the chemical and physical characteristics of concrete.
