Abstract
We studied fundamental properties, operation methods, and leachability of a cement solidification of municipal solid waste incineration fly ash (MSWI fly ash) contaminated with radiocesium. It was clarified that ordinary cement mix method can be adopted to the cement solidification of the MSWI fly ash. The leachability of the cement solidification MSWI fly ash decreases with increasing of the unconfined compressive strength; it is in a linear relation, so that we can predict the leachability from the compressive strength. From these results, we proposed a cement mix design method of the MSWI fly ash contaminated with the radiocesium.
