Cement: Materials and manufacturing process

A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement. The cement is bagged transported for concrete production.

Cement Industry Overview

The cement industry is the building block of the nation's construction industry. Few construction projects can take place without utilizing cement somewhere in the design. Annual cement industry shipments are currently estimated at $7.5 billion for 2012; up from $6.6 billion in 2011. U.S. cement production is widely dispersed with the operation of 107 cement plants in 36 states. The top five ...

Environmental impact of concrete - Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

UK Concrete and Cement Industry Roadmap to Beyond Net Zero

Concrete is a mix of aggregates, cement and water. The principal ingredient in cement is clinker. Clinker production is the main source of carbon dioxide emissions. These arise from the combustion of fuels in the kiln and from ‘process emissions’ which are a by-product of the chemical reaction that makes clinker.
