Sintered Fly Ash Light Weight Aggregate Production
Adopted process uses above 90% fly ash mixed with water and in some cases a small volume of additives. After agglomeration and pelletizing, the green pellets are sintered at high temperature, producing light weight aggregate whose characteristics are similiar to natural aggregates.
