Cement Energy and Environment

7. Conclusion AFR Utilization and co processing in cement industry has become the need of hour. Cement plants are dedicated to replace more and more non-renewable fuel by alternative fuel and hazardous waste. Detailed study of physical and chemical properties of AFR and its impact on cement manufacturing process and quality is a must before using it. Use of alternative fuels and raw materials also helps in achieving tough PAT targets in PAT cycle-11. ••••• Have long lite ot 30- 40 yeara with proper quality control Require very low maintenance Load carriers plying on CC Roads sllve up to 14 per cent fuel Do not get damaged by heavy rainfall or high temperatures Invariably cheaper than bitumen roads In llfe·cyde cost. Non·pollutlng and us er friendly Competitive even on initial cost basis Being lighter in colour require lower illumination Rate of Increase of ambient temperature Is r·educed by adopting Cement Conc rete ROllds Good riding quality Concrete Roads Recently Constructed Mumbal City Roads - 650 km.
