Cured compacted products suitable for use as landfill materials, embankments, roadbase compositions and the like are produced by the described method from fly ash-containing waste materials obtained by a lime based dry scrubbing flue gas desulfurization operation. In this method the dry fly ash-containing waste powder, which also contains calcium sulfite or sulfate reaction products and unreacted lime, is contacted with a predetermined amount of water and mixed under critical mixing conditions to provide a powder/water mixture which is placed at a suitable utilization site, e.g., a landfill disposal site, and compacted under sufficient load to achieve at least about 70% of the laboratory dry density. The resulting products have compressive strengths after curing of at least about 25 psi and permeabilities of less than 1.times.10.sup.-5 cm/sec.
