Overview of waste stabilization with cement

摘要: Cement can treat a variety of wastes by improving physical characteristics (solidification) and reducing the toxicity mobility contaminants (stabilization). Potentially adverse waste-binder interactions are an important consideration because they limit solidification. Stabilization occurs when contaminant is converted from dissolved (mobile) phase to solid (immobile) reactions, such as precipitation, sorption, or substitution. These reactions often strongly affected pH, so presence components waste that control pH critical stabilization reactions. Evaluating environmental impacts be accomplished in tiered strategy which simplest approach would measure maximum amount could released. Alternatively, sequence release determined, either microcosm tests attempt simulate conditions disposal zone mechanistic models predict behavior using fundamental treated waste.
