Artificial aggregates produced by using waste materials are a suitable alternative to natural aggregates. This work proposes a multi-criteria decision model to select artificial aggregates (AASs) through an experimental process. The integrated environmental (LCA) analysis was carried out for artificial aggregates to choose the most suitable aggregate. Three different mix design were developed by using cement (5%, 10%, 15%), fly ash (80%) (obtained from municipal waste incineration plant), ground granulated blast furnace slag (5%, 10%, 15%), and marble sludge (70%). According to the outcomes the AASs with 80% FA, 5% GGBFS and 15% OPC are the most suitable solution.

摘要

Artificial aggregates produced by using waste materials are a suitable alternative to natural aggregates. This work proposes a multi-criteria decision model to select artificial aggregates (AASs) through an experimental process. The integrated environmental (LCA) analysis was carried out for artificial aggregates to choose the most suitable aggregate. Three different mix design were developed by using cement (5%, 10%, 15%), fly ash (80%) (obtained from municipal waste incineration plant), ground granulated blast furnace slag (5%, 10%, 15%), and marble sludge (70%). According to the outcomes the AASs with 80% FA, 5% GGBFS and 15% OPC are the most suitable solution.
