Description:
The stabilization/solidification of hazardous wastes involves a series of chemical treatment procedures. The waste is normally treated so as to complex or bind the contaminants into a stable, insoluble form (stabilization), or to entrap the waste material in a solid and/or crystalline matrix (solidification). azardous wastes contain many constituents that could interfere with the binding process. This project is concerned with identifying possible interference mechanisms between particular waste components and commercially available waste-binding systems. This report presents a literature review and information concerning portland cement and pozzolan chemistry, the effects of added constituents (admixtures) on their setting characteristics, and the effects of typical organic waste components on the physical and containment properties of the treated waste product. hese topics are presented so that conclusions may be drawn as to possible types of interference materials that might be encountered in typical waste/binder systems. lso included are a glossary of common cement terminology and three bibliographic appendices covering a compilation of references and annotated citations for both Portland cement and asphaltic waste treatment systems.
