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