Bogue calculation - Understanding Cement

The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. Although the result is only approximate, the calculation is an extremely useful and widely-used calculation in the cement industry. The calculation assumes that the four main clinker minerals are pure minerals with compositions:

Portland cement clinker - overview

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Raw materials for cement manufacturing

Sulphates may be present in clinker up to about 3%. Sulphur in raw materials increases SOx emission and cause build-up in preheater. Sulphate can form a stable compound with Potassium (K2SO4) and to lesser extent Sodium (Na2SO4). The sulphates in the clinker comes from raw materials and fuel.

3.5 Properties of the major cement minerals

Clinker, during construction of buildings throughout the ages, cement was always preferred as one of the important building materials. It combines with different components such as cement, sand and water, then becomes a mortar, and when used in the structure, it dries after a certain period of time to provide the desired hard floor.
