The major objective of this project is to demonstrate the suitability of using ultra-lightweight aggregates (ULWA) produced by thermal expansion of solid residues (slag) generated during the gasification of Illinois coals as substitutes for conventional aggregates, which are typically produced by pyroprocessing of perlite ores. To meet this objective, expanded slag aggregates produced from an Illinois coal slag feed in Phase I will be subjected to characterization and applications-oriented testing. Target applications include the following: aggregates in precast products (blocks and rooftiles); construction aggregates (loose fill insulation and insulating concrete); and other applications as identified from evaluation of expanded slag properties. The production of value-added products from slag is aimed at eliminating a solid waste and possibly enhancing the overall economics of the gasification process, especially when the avoided costs of disposal are taken into consideration.
