The second approach consists in the substitution of fuels, raw materials and the clinker used in the cement production process (Benhelal et al. 2013). High-process temperature of cement kilns can help combust waste well. Thus, the utilization or co-combustion of waste or biomass materials as alternative fuels can contribute to reduce …Web

The raw material was configured with clinker rate value KH = 0.92, SM = 2.1, IM = 1.2 and leaching residue content of 26.98%. The f-CaO content was less than 2% in the cement clinker prepared at 1400 °C and less than 1% in the cement clinker prepared at 1450 °C. This indicated that the raw material had good burnability.Web
