Fly ash from municipal solid waste incineration (MSWI) is classified as hazardous waste. However, the fly ash has showed pozzolanic behavior, and therefore it has been investigated whether MSWI fly ash may partly substitute cement in Portland cement mortar after upgrading the MSWI fly ash by electrodialytical removal of metals and salts. The influence of MSWI fly ash according to workability, strength and heat evolution has been investigated. It was shown that MSWI fly ash has potential for
