Calcite is widely distributed and a major mineral of calcareous sedimentary (limestone) and metamorphic (marble) rocks. Some magnesium substitution for calcium is permissible, creating magnesian calcites. Limestone is used in cement, gravel, and building stone, and in agriculture as 'aglime' for raising soil pH.

The binding medium is usually a cement water paste. The mineral filer or rock particles which are suspended in paste are called aggregates. Aggregates can range in size from grain of sand to a stone several inches in diameter. The purpose of the paste is to fill the voids in between the aggregates and to give the strength to the hardened concrete.
