Environmental Pollution Remediation through Solidification/Fixation of Heavy Metal Ions in Portland Cement

Abstract

Manish Kumar Goyal and Ashish Chauhan

Treatment of hazardous wastes existing as effluent using cement-based solidification/stabilization is an effective option for remediating environmental pollution. Among the various treatment techniques, it is one of the most widely acknowledged methods for treating the wastes. The primary objective of this review is to survey our current knowledge in this subject, focusing on cement chemistry, the effects of inorganic (heavy metals) and organic compounds on cement hydration and the mechanisms of immobilization of different organic and inorganic compounds.
