Feasibility Study on Spent Pot Lining (SPL) as Raw Material in Cement Manufacture Process
Different mix was designed with varying dosages of SPL. The burnability investigations of raw mix showed free lime content of 1.58 for 0%, 1.03 for 0.5%, 0.74 for 1%, 0.68 for 1.5% and 0.44 for 2% at 1450C. The result cement compressive strength of 21.8, 31.0 and 45.6 MPa at 2, 7 and 28 days. The performance characteristic showed conformity to OS: 7 2001 for 42.5 grade of Ordinary Portland Cement.
Keywords: SPL, clinker, burnability, free lime, compressive strength
