Abstract

The negative effects of unburned fabric in municipal solid waste incinerator (MSWI) ash on the performances of cement composite were investigated. The chemical and physical characteristics of MSWI ash powder containing high volume of unburned fabric were analyzed. The workability and compressive strength of mortar-type cement composites with the ash powder were evaluated. The workability of the cement composites was decreased mainly by unburned fabric in the ash, while the compressive strength was decreased by MSWI ash itself. From the experimental results, the critical limits for both MSWI ash and their powder containing unburned fabric in the cement composites should be limited from standpoint of the workability of the composite.
