Abstract

Coal combustion in boilers generates ash as a byproduct, either as bottom ash or fly ash. Fly ash can be used to produce brick products instead of being thrown away. Although used worldwide, Autoclaved Aerated Concrete (AAC) contg. fly ash was only introduced in the United States 15 years ago. It was first developed in Sweden and has been used throughout Europe for the past 70 years as well as the Far and Middle East for the past 40 years. The Illinois State Geol. Survey AAC project team is currently working with Babb International, the leading AAC producer in the United States, to develop a process that focuses on using Illinois coal fly ash for producing AAC brick products. In this project, fly ash is used as a raw material to substitute sand, the main ingredient of regular AAC products.
