Rice hull ash for cement admixture |
| abstract |
Rice hull ash for cement admixtures which has a high pozzolan activity and can be efficiently and easily produced in a short time, a process for producing the ash, and a cement composition containing the ash for cement admixtures. A rice hull powder obtained by pulverizing rice hulls to an average particle diameter of 20 µm with a pulverizer (11) was stored in a rice hull powder storage tank (12). The rice hull powder was then blown together with air into the combustion furnace of a suspension firing boiler (13) and burned at 900ºC for 5 seconds. Thereafter, the flue gas and fly ash discharged from the suspension firing boiler (13) were passed through an electric dust collector (14) to thereby isolate rice hull ash for cement admixtures from the flue gas and fly ash. |
