Physical, geometrical and chemical characterisation of incinerator bottom ash towards its use as recycled aggregate
Physical, geometrical and chemical characterisation of incinerator bottom ash towards its use as recycled aggregate
This work performs an extensive characterisation of incinerator bottom ash (IBA), analysing its physical, geometrical and chemical properties. Experiments included the determination of particle size distribution, flakiness and shape indexes, particle density and water absorption, the chemical analysis of the residue and also its leaching behaviour. The latter comprised, among others, the quantitative determination of different chemical species. The results obtained in the chemical analyses were compared with the limit values established in the European legislation for inert and non-hazardous waste classification. The outcomes of the investigation revealed that some properties of IBA were unsuitable for its use as recycled aggregate. To be a viable alternative to natural aggregates, IBA would need at least some preliminary treatment.
