Resumen

The microstructure and mineralogy of lightweight aggregates manufactured with washing aggregate
sludge, sewage sludge and a clay-rich sediment have been studied. The mineralogical analysis revealed
the neo-formation of plagioclase and pyroxene group minerals and a minor presence of gehlenite. Some
relationships may be established: (i) heating temperature and dwell time affect the formation of new
porosity; (ii) the disappearance of pyroxenes could produce changes in the density of the solid material
in the lightweight aggregates; (iii) when an external glassy film is not present, water absorption values
depend on the size and number of each type of pore.
