Limestone is a type of a sedimentary rock that is found naturally in the earth''s environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO 3) in the form of calcite which is yet again a type of a also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.
Main Uses of Limestone: In Missouri, limestone of all kinds is used mainly for aggregate (aka "gravel") that is produced by crushing and screensizing limestone quarry rock. The aggregate is used in concrete, for road surfacing (with or without asphalt or tar binder), and for foundation support beneath weightbearing structures.
Mar 26, 2015· The added limestone in the is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding.
Aug 12, 2014· The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace ().. Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). ...
