Stabilization/solidification of municipal solid waste in cemented matrices

Abstract

The exponential increase that has been unchained in the generation of municipal solid wastes, in these last years, and that they need to be treated and management appropriately, it has forced to act immediately as for the management of this type of wastes. One type of these wastes is the wastes coming from Municipal Solid Wastes Incineration. One of the most useful methods to management its, is by means of stabilization/solidification systems. In that aspect it shows up this work in which has been used cement-based materials as immobilization system. Among the different kinds of cementitious materials to be employed in the solidification of wastes, the ordinary Portland cement is the most frequently employed. The main objective of this paper is to quantify the grade of immobilization grade of hazardous wastes, by means of the pore solutions analysis.
