Thermodynamics of Clinker Formation

2021-5-15  This reaction is also endothermic - but less so. As with the first reaction, the standard enthalpy change here can be calculated using the table provided. This time it's 115.08 kJ/mol (of CaCO 3) or 1.1498 MJ/kg.. Poor Martin was entirely unaware of data on the enthalpies of formation of the silicates (), and in 1925 the nature of the minerals in clinker was by no means settled - many believed ...

LSF Formula - Page 1 of 3 - CemNet

This calculation is based on the hypothesis that the main oxides in clinker are four (s,a,f,c) and that they combine in four phases (c3s,c2s,c3a,c4af). (the intitial assumption) If you have a certain mix of the four main oxides (s,a,f,c), you can calculate how much of the four clinker phases you can get from that: (c3s,c2s,c3a,c4af).

Question: How Do You Calculate Clinker Factor ...

2021-10-31  How do you calculate lime saturation factor? 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/ (2.8SiO2 + 1.2Al2O3 + 0.65Fe2O3) Often, this is referred to as a percentage and therefore multiplied by 100.
