Uses of ordinary portland cement It is used for general construction purposes, where special properties are not required like reinforced concrete buildings, bridges, etc. Also used in most concrete masonry units. It is also used as a basic component in mortar, plaster, and non-specialty grout.
Grinding Aids are used in the cement mill Ball Mill, Vertical Roller Mill, HoroMill to increase the productivity, save electrical energy andor to increase the fineness and improve defined cement properties, e.g. powder flowability. A typical example is SikaGrind -400.
In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature 2,500 to 2,800 degrees Fahrenheit in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds.
Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.
The company uses Vertical Roller Mill VRM technology from Flsmidth, Denmark.
