Abstract

A solidification/stabilization process is described, said process having the aim of encapsulating harmful and toxic waste containing heavy metals, using a mixture composed of hydraulic cement, aggregate, bentonite and an additive having a combined action promoting fluidization and accelerating setting. The bentonite has the effect of immobilizing the pollutants by means of a dual absorption and iron-exchange action, whereas the use of the fluidizing/accelerating additive allows better control of the setting operation and the use of a smaller quantity of water resulting in an improved mechanical performance and an increase in the durability of the end product which may be disposed of in controlled waste tips for toxic waste with a low level of toxicity or which may be used as a construction material.
