  • Overview of the Concrete Hydration Process

    Overview of the Hydration Process. The hydration of cement can be thought of as a twostep process. In the first step, called dissolution, the cement dissolves, releasing ions into the mix water. The mix water is thus no longer pure H2O, but an aqueous solution containing a variety of ionic species, called the pore solution.

  • Cement Production an overview | ScienceDirect Topics

    The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.

    A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. There are two main forms of cement: Geopolymer cement and Portland is seldom used on its own, but rather to bind sand and gravel mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.

  • Clinker cooler – level and pressure measurement | VEGA

    To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air.
