Cement: Materials and manufacturing process

• Chalk is porous and often has high moisture content that leads it to its use in the ''semi-dry/wet'' manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.

11.6 Portland Cement Manufacturing

1971-8-17 · The initial production step in portland cement manufacturing is raw materials acquisition.Calcium, the element of highest concentration in portland cement, is obtained from a variety ofcalcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impurelimestone known as "natural cement rock". Typically, these raw materials are obtained from open-facequarries, but underground mines or dredging operations are also used. Raw materials vary fromfacility to facility. Some quarries produce relatively pure limestone that requires the use of additionalraw materials to provide the correct chemical blend in the raw mix. In other quarries, all or part ofthe noncalcarious constituents are found naturally in the limestone. Occasionally, pockets of pyrite,which can significantly increase emissions of sulfur dioxide (SO2), are found in deposits of limestone,clays, and shales used as raw materials for portland cement. Because a large fraction (approximatelyone third) of the mass of this primary material is lost as carbon dioxide (CO2) in the kiln, portlandcement …
