Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3 ). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a ...

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry''s CO 2 emissions are caused by transformation of limestone into lime, called "decarbonation". Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

 · Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone to some extent. According to some estimates, around 1.5 tons of limestone is required to produce a ton of cement.

Specification for Portland Cement, w a s withdrawn and revised to more clearly define limestone and require cement manufacturers to report the quantity of limestone in the cement. These changes are reflected in a revised letter ballot issued in October 1997 and can-vassed in November 1997 (see box be-low for text of the proposed change).

 · Table 1 below lists the five main chemical compounds in cement and their average percentages by weight. These compounds develop from limestone or lime and clay as a consequence of pyroprocessing. Most hydraulic cements are based on basic calcium compounds that are easily hydrated (Gartner and Macphee, 2011).Limestone is based mainly on calcium carbonates.

In 2006, 267.5 million tonnes of cement, with a value of EUR 19 billion, were produced in the EU by 356 installations. The EU cement industry in 2006 represented 10.5% of total world production. This decreased to 5.6% of world production in 2011 (195.5 Mt) however. Large cement plants produce some 4 000 tonnes of cement per day.

If cement could be made without limestone, theoretically, that could eliminate many of the industry''s CO2 emissions. Typically, when water is added to Portland cement and gravel to make concrete, it reverses the reaction that occurred in the cement kiln—almost—in a process called "curing."6 Dec 2017

 · In the cement industry, however, this link is weak. The industry''s record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent. Behind the lackluster ROIC, two drivers stand out: high goodwill (seen in the low tangible capital ratio) and inadequate capital efficiency. Call it bad timing.
