Used aggregate residues result from the combustion of refuse. The structure and particle composition are the same as natural aggregates. The chemical composition of the MSWI (Municipal Solid Waste Incineration) is dominated by elements Si, Ca, Al and Fe. These elements are similar to those commonly found in a cement matrix. The characteristics of these materials are defined by testing and measuring the density, the absorption coefficient, the water content of the aggregate, the “Micro-Deval” coefficients and the grain-size distribution. The Dreux-Gorisse method is used in order to obtain the formulation of the composition of a normal and a MSWI concrete. The substitution of natural aggregates is governed by those of the MSWI. Concrete samples are prepared and submitted to compression and tension tests. Mechanical performances at different states are deduced from the tests results.
