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 is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg (CO 3) 2 ). It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil ...

Quarrying is quite simply the extraction of natural resources from the earth, usually from some form of surface working or quarry site. Quarries produce a range of useful materials, including limestone, dimension stone and rock. In Australia, the most common materials extracted are construction aggregates such as crushed rock, sand or gravel.

Limestone aggregate as the main building materials has been concerned for a long time. Due to the backward techniques, limestone had not been processed perfectly, but with the development of science and technology, more and more advanced techniques have been applied to the mining machinery industry.

HISTORY OF CEMENT. The word "cement" is derived from the Latin word "caementum", which means chipped rock fragments. Limestone is well known to be the oldest material to be used as a binder. Lime was produced by heating near pure limestone, and lime mortar was created by adding and mixing water and sand. Concrete was first used in the ...
