摘要
The process for the production of geopolymer cement from fly ash and granulated blast furnace slag uses very high proportion (60 to 95%) of industrial waste such as fly ash and granulated blast furnace slag. In the process granulated blast furnace slag is fine grounded and/or mechanically activated in conventional grinding mills or high-energy mills. The fly ash, which is found in powder form and fine powder of granulated blast furnace slag, is thoroughly mixed with sodium or potassium based alkaline activator and water. The paste is cured at room temperature during which the dissolution of silica and alumina present if fly ash and granulated blast furnace slag starts. After the initial dissolution, the paste is heat treated at the temperature in the range of 60-200 degree C. The process does not require large energy consumption and also produces no CO2 emission. Also the processing steps are simple and easy.[IN-DEL-2006-00728A]
