Lecture: 24 Cement industries Dr. N. K. Patel N P T E L 165 About onethird of the raw meal mass can be attributed to Loss on Ignition (LOI), which is almost exclusively due to the calcination of the CaCO 3 used as a precursor for forming CaO. This corresponds to the fact that the raw meal contains about 75 wt% of CaCO 3.
