LWA demonstration applications using Illinois coal gasification slag: Phase 2. Technical report, September 1--November 30, 1993

The objectives of this program are to demonstrate the feasibility of producing ultra-lightweight aggregates (ULWA) from solid residues (slag) generated during the gasification of Illinois coals, and to test the products as substitutes for conventional aggregates produced by pyroprocessing of perlite ores. In Phase 1 of this project, Praxis developed a pilotscale production technique and produced a large batch of expanded aggregates from an Illinois coal slag feed. The Phase 2 work focuses on characterization and applications-oriented testing of the expanded slag products as substitutes for conventional ULWAs. Target applications include high-volume uses such as loose fill insulation, insulating concrete, lightweight precast products (blocks), waterproof wallboard, rooftiles, and filtration media. The precast products will be subjected to performance and characterization testing in conjunction with a commercial manufacturer of such products in order to obtain input from a potential user. The production of value-added products from slag will eliminate a solid waste and possibly enhance the overall gasification process economics, especially when the avoided costs of disposal are taken into consideration.
