Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are
Calcination is the core portion of the process, in which huge rotary kilns come into play. Inside, at 1400 degrees C, the raw material is transformed into clinker: small, dark gray nodules 3

Jul 08, 2013· CURING OF CONCRETE The process of keeping concrete wet to enable it to attain full strength is known as curing. The objective of curing is to prevent loss of moisture from concrete due to evaporation or because of any other reasons. Curing should be done for a period of three weeks but not less then 10 days. 40.

Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.
Although the process for cement manufacture is relatively similar across North America and much of the globe, the reference to cement specifications can be different depending on the jurisdiction. In addition, test methods can vary as well, so that compressive strength requirements (for example) in Europe don’t ‘translate’ directly to
