Reducing Clinker Content and Carbon Footprint of Concrete ...

• Portland Cement is manufactured from limestone and shale rocks that have been fired at 1450 C to form a synthetic rock called clinker. This clinker is then crushed to a powder. • When limestone is heated, it gives off CO 2. –CaCO 3 CaO + CO 2 • This reaction is unavoidable in the manufacture of cement clinker • So to reduce CO 2 the ...

Chemicl parameters defining clinker composition

Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/ (2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker.
