Cement industry - razi-center

The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble. Non-hydraulic cements (e.g. gypsum plaster) must be kept dry in order to retain their strength. The heart of concrete lies in the cement.

Cement provides the chemical bonds that hold the other materials together to form a dense rocklike substance. Concrete is the world's most commonly used construction material and second only to water as the most-consumed substance on Earth. Demand for cement is directly tied to the use of concrete in building construction and public works projects.

Cement composition and classification - PetroWiki

Cement composition and classification. A slurry of Portland cement in water is used in wells because it can be pumped easily and hardens readily, even under water. It is called Portland cement because its inventor, Joseph Aspdin, thought the solidified cement resembled stone quarried on the Isle of Portland off the coast of England.
