Samenvatting

The use of industrial by products such as municipal solid waste incineration (MSWI) bottom ash in concrete aims to incorporate materials with less CO2 impact, reduce the amount of waste material landfilled and lower the need for natural raw materials in concrete production. However, the environmental impact of the MSWI bottom ash itself needs to be considered, since both concrete constituents and final concrete products need to comply with the existing European and Dutch legislation. Therefore, the leaching of contaminants needs to be studied, and its effects on the hydration of cement quantified. XRD analysis can be a powerful tool in this regard, but challenges can arise due to the complex and often varying composition of MSWI bottom ash. For this reason it is necessary to combine other characterisation techniques such as SEM/EDX. Element mapping and PARC phase mapping were employed to identify the phases present in a fine fraction of MSWI bottom ash (0-4mm) which are mainly quartz, calcite, several types of melilites, iron oxides, bottle glas, iron oxides and residues from incinerated rubber.
