Bogue calculation - Understanding Cement

The Bogue calculation is used to calculate the approximate proportions of the four main minerals in Portland cement clinker. The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement.

Modifying the Bogue calculation - International Cement

2018-1-31  The Bogue calculation is a means of allocating the four main oxides in Portland cement clinker to the four main phases present after firing in a cement kiln. The calculation is based on the assumption that the phases are present as pure tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetra-calcium alumino-ferrite and that the ...

Bogue calculations[1] because the calculations assume that each of the four mineral phases (alite, belite, aluminate, and ferrite) are chemically pure. Actual uncertainties in phase estimates by Bogue calculation stem from a combination of sources: bulk oxide measurement uncertainties, differences between assumed phase and actual composition ...

Cement hydration - Understanding Cement

Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating ...

Analysis of cement - Understanding Cement

Cement analysis: X-ray fluorescence (XRF) The basic principle of XRF analysis is simple. (The physics of what happens is complex, but we won't concern ourselves too much with the details.) If we zap a sample of, say, cement with a beam of X-rays, the X-ray beam will cause other X-rays to be generated within the cement.
