Cement - Sympatec

By addition of water, cement turns into cement paste, which hardens through hydration to durable cement stone. The cement industry faces challenges such as assurance of consistent, grade-specific quality and furthermore energy and resource efficiency.


In addition, a basic review of the cement production process was developed, and summary cement industry energy and economic data were collected, and analyzed. The remainder of this report is organized as follows: • Section 2 summarizes California cement industry statistics • Section 3 provides an overview of the cement production process

How Concrete is Made - cement.org

Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete. The strength of the paste, in turn, depends on the ratio of water to cement. The water-cement ratio is the weight of the mixing water divided by the weight of the cement.

Cement Production Process - Cements in India

Process of mixing ingredients: Measured amounts of the coarse and fine aggregates are mixed together. A measured amount of cement is added and mixed in. Enough water is added to make the mix workable. All the materials are then mixed together well. The cement powder and water form a paste which bonds the aggregates together like glue.
