The study was undertaken to decipher the mechanisms of solidification/stabilization (S/S) of water soluble organics, namely, phenol and ethylene glycol. Portland cement Type I was the binder used in ratios that varied from 2% to 50% organics/waste mixture. The S/S product was studied at various intervals using optical microscopy, scanning electron microscopy, x-ray power diffraction, energy dispersive elemental analysis, transmission electron microscopy and several physical tests. The organics are not effectively immobilized toward water leaching. Effects on the matrix are very concentration dependent and are much more dramatic with ethylene glycol than with phenols. Although there is evidence of chemical reaction between the phenols and the fixing agents, the reaction does not result in chemical fixation of the organic.
