Chemistry and Microstructure of Solidified Waste Forms presents a comprehensive summary of mechanisms of immobilization in cementitious waste forms and the effect of waste species on cement chemistry and morphology. The book introduces the well-known chemistry and microstructure of cement pastes, in addition to common mechanisms of immobilization of waste species in cementitious waste forms. The fundamental chemical and microstructural fate of waste species is reviewed, and a technique for studying cementitious waste forms using scanning transmission electron microscopy (STEM) is described with examples of its application.
Chemistry and Microstructure of Solidified Waste Forms also presents evidence to prove that chromium in waste becomes part of the cement matrix, and the potentially harmful effect of this process is discussed. Data for interpretations are included so that other researchers can analyze the data and draw their own conclusions. The book also discusses how solubility and solubility theory can be combined with leach theory and diffusion theory to predict the leaching performance of cementitious waste forms.
Chemistry and Microstructure of Solidified Waste Forms will prove invaluable to hazardous waste professionals, engineers, environmental engineers, chemical engineers, waste disposal managers, waste form developers and researchers, and regulators.
