ABSTRACT:
An abrasion resistant synthetic aggregate made from an intimately intermixed combination of lime, fly ash and sulfate/sulfite sludge (e.g. FGD sludge), mixed to the point where the mixture is nearly optimum density and compressible or non-compressible and plastic. This mixture is placed in a landfill. After a relatively brief cure period, the landfill is ripped and the material is crushed and graded. The aggregate, which in some instances may qualify as a light weight aggregate, has a Los Angeles Abrasion Resistance of less than 60%, and may in some cases be less than 50% (medium particles passing) according to that test.
