calculate oxides in clinker

The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/(2.8SiO2 + 1.2Al2O3 + 0.65Fe2O3).

Portland cement clinker: the Bogue calculation

The calculation is simple in principle: Firstly, according to the assumed mineral compositions, ferrite phase is the only mineral to contain iron. The iron content of the clinker therefore fixes the ferrite content. Secondly, the aluminate content is fixed by the total alumina content of the clinker,

Calculating CO2 process emissions from Cement

2019-12-31  Carbon dioxide (CO2) is emitted from both the chemical process and energy consumption associated with the manufacturing of cement. During calcination or calcining, calcium carbonate (CaCO3) is heated in a cement kiln to form lime, a process that emits CO2 as a byproduct. The resulting lime reacts in the kiln with silica, aluminum, and iron oxides present in the raw material to produce clinker. Clinker, an intermediate product, is mixed with a small amount of gypsum and/or anhydrite to make Portland cement. Some varieties of masonry cement
