A powder of alumina silica lime iron oxide and magnesium oxide burned together in a kiln and finely pulverized and used as an ingredient of mortar and concrete the adhesive or glue that holds concrete together concrete a hard strong building material made by mixing a cementing material as portland cement and a mineral aggregate as sand and gravel with sufficient water to cause the cement to set and bind the entire mass cement is part of concrete.

Abstract the current world consumption of cement is about 15 billion tonnes per annum and it is increasing at about 1 per annum the electrical energy consumed in cement production is approximately 110 kwhtonne and around 40 of this energy is consumed for clinker grinding there is potential to optimise conventional cement clinker grinding circuits and in the last decade significant.

And alumina finished cement is produced by finely grinding together around 95 cement clinker with 5 gypsum or anhydrite which helps to retard the setting time of the cement the quality of cement clinker is directly related to the chemistry of the raw materials used around 8090 of raw material for the kiln feed is limestone.

In the wet process water is added to the raw mill during the grinding of the raw materials in ball or tube mills thereby producing a pumpable slurry or slip of approximately 65 percent solids the slurry is agitated blended and stored in various kinds and sizes of cylindrical tanks or slurry basins until it is fed to the pyroprocessing system the heart of the portland cement manufacturing process.
