A COMPOSITE OF GAMMA-DICALCIUM SILICATE FOR CO2 CAPTURE COMPRISING FLY ASH OF FLUIDIZE-BED BOILER AND MANUFACTURING METHOD THEREOF

摘要

Provided is a gamma dicalcium silicate composition for capturing carbon dioxide, which is produced by; forming clinker by mixing ingredients with 15-25 parts by weight of water with respect to 100 parts by weight of the ingredients, wherein the ingredients comprises 35-70 wt% of fluidized-bed boiler fly ash, 25-50 wt% of waste foundry sand powder ground to have the particle size of 1,000-2,000 blaine (cm^2/g), and 5-15 wt% of paper ash powder ground to have the particle size of 1,000-2,000 blaine (cm^2/g), with respect to the total weight of the clinker based on solid; and drying and sintering the same thereafter. In addition, provided is a production method thereof.
