Cost of Klinker Against C3S

The document compares the cost savings from decreasing C3S content versus using additives in two cement kiln lines. For kiln line I, decreasing C3S by 6% saves 86470.59 rupees per day, while using 12% additives saves 539208.24 rupees per day, a difference of 452737.65 rupees. For kiln line II, decreasing C3S saves 106852.82 rupees, additives save 458568.24 rupees, a difference of 351715.42 rupees. Using additives provides greater cost savings compared to decreasing C3S alone for both kiln lines.
