This study replaced natural fine aggregate with a fine aggregate of washed municipal solid waste incinerator bottom ash (WMSWIBS) in the production of compressed mortar paving units to explore the feasibility of using WMSWIBS in this application. Cement-aggregate ratios (c/a) of 0.1, 0.2, 0.3, 0.4, and 0.5 and water-cement ratios (w/c) of 0.20, 0.25, and 0.30 were selected. The results yielded a specific gravity of 2.21, aggregate absorption of 9.6%, and a fineness modulus of 3.2. The WMSWIBS's toxicity characteristic leaching procedure (TCLP) values were much lower than the limit specified by the Environmental Protection Administration (EPA, Taiwan), and its …
