What is the volume increase with S/S applications?
Volume increase is often not as great as one would think in field application of cement-based S/S. It is dependent on several factors including void space in the untreated waste, water content of untreated waste, and compaction after treatment. In Jesse Conner’s book Chemical Fixation and Solidification of Hazardous Wastes, he writes, “In general, volume increase for cement-based CFS systems equal about 0.4 times the weight increase; that is, 10 percent volume increase equals 25 percent weight increase (mix ratio of 0.25) This applies to water saturated wastes only. Dry ashes and dusts may actually see a volume decrease due to lowered void space when the material is wetted.
