Abstract: An Illinois coal ash, which has metals and a large amount of iron, is considered to be an especially difficult waste for disposal.
In the process described in this paper, the high iron and metal content is used to create a building material with special properties.
The metals are sequestered.
The metals allow a process that creates valueadded products, building materials.
The products are inexpensively prepared colored, strong, lightweight insulative structural panels.
By either sintering in an oven at 725°C or by adding a flux and sintering at 525°C, panels are produced which will not leach metals from the ash.
The use of an acid with the fly ash as a flux was investigated in comparison with fly ash control samples.
The effects of sintering samples at different temperatures and with or without vacuum were also observed.
Properties of the samples, including values for strength, water absorption, insulation, and presented from this study.
