It is the ratio of the percentage of lime to the volume of silica, alumina and iron oxide. For OPC, the minimum lime saturation factor for 33 grade and 43 grade cement is 0.66 % while for 53 grade cement, it is 0.8 %. The maximum lime saturation factor 33 grade, 43 grade and 53 grade cement is 1.02 %. 2.
