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. During this reporting period, major accomplishments were the selection of mix designs and test methods for preparation of specimens of expanded slag for testing in precast applications (Task 3) and construction aggregate applications (Task 4). In addition, characterization data (Task 1) were,analyzed, and evaluation of the expanded slag products as substitutes for conventional ULWAs (Task 2) was completed. Potential applications that were identified are: (1) Loose fill insulation; Insulating concrete (roof, floor, and walls); Precast products (blocks and rooftiles). Experimental work during the project is focused on these applications.
