Cement is produced by a high-temperature (about 1500 °C) reaction in a rotary kiln of carefully proportioned and blended ratios of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3).The production of cement is a chemical process requiring an accurate blend of the previously cited four key organic oxides and the …
First and foremost, clinker is an extremely hard and abrasive material. This means that it is difficult to grind down into the fine powder that is needed to make cement. Crushing the clinker is the first step in this process, as it reduces the size of the clinker particles and makes them easier to grind.
Portland cement is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of gypsum (calcium sulphate dehydrate – CaSO4.2H2O, which controls the set time) and other minor constituents which can be used to vary the properties of the final cement. The standard Portland cement is often referred to as ...
