What is white cement. Characteristics and fields of ...
Light coloring of cement is achieved by using raw materials where there are no glandular compounds or are present, but in a small amount. White cement is produced on the basis of low-iron clinker, where the content of manganese and chromium is minimized. It also includes mineral additives, limestone, gypsum, chlorinated salts, which give it a whitish color.
Cement Raw Materials used in Manufacturing of …
Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale. Let’s understand the various types of cement raw materials ...

Cement - History of cement | Britannica
Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.

Portland cement - Wikipedia
Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker. The materials in cement clinker are alite, belite, tri-calcium aluminate, and tetra-calcium alumino ferrite. The aluminium ...
