The major objectives of the HAZCON Solidification SITE Program Demonstration Test were to develop reliable performance and cost information. The HAZCON process mixes the hazardous waste material with cement, a proprietary additive called Chloranan and water. The Chloranan is claimed to neutralize the inhibiting effect that organics normally have on the hydration of cement. The technical criteria used to evaluate the effectiveness of the HAZCON process were contaminant mobility, based on leaching and permeability tests; and potential integrity of solidified soils, based on measurements of physical and microstructural properties. Extensive sampling and analyses were performed showing the concentration of the organics were the same in the leachates of the untreated and treated soils, heavy metals reductions were achieved, and structural properties of the solidified cores were found to indicate good long-term stability. The volume contains data collected during the project.
