Limestone Portland CementCosts & Benefits
|Parent Process: Blended Cement Alternatives|
|Energy Savings Potential||
For a cement with 25 to 35% by mass limestone, thermal energy demand will decrease by 0.22 to 0.60 GJ/t-cement. Electricity demand will also decrease by 12–23 kWh/t-cement
|CO2 Emission Reduction Potential||
For a cement with 25 to 35% by mass limestone, direct and indirect CO2 emission reductions can be 50 to 140 t CO2/t-cement and 6 to 16 kg CO2/t-cement.
Capital costs for extra storage capacity for the other main constituents and the new cements as well as the technical equipment for handling and drying of these constituents may be € 8-12 million.
