Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Limestone types may be formed either inorganically or biochemically and include coral reefs, chalks, coquina and oolitic limestone. Limestone is composed of calcite and makes up approximately 10 percent of all sedimentary rocks. Limestone is found in many parts of the world, both on land and in water, including Central America and England.
Limestone as Dimension Stones: We know limestone can be cut into pieces of any dimension. Whole stones or cubes also prove better structural material and gives the property a classic look.
