The objectives of this study are to evaluate the solid wastes from fluidized bed combustion for potential commercial uses, and to explore methods by which the material can be safely disposed of. Most of the current activity is related to preparation for the forthcoming construction of the experimental road base sections in Columbus, Ohio, or to the production of synthetic aggregates by briquetting and/or extrusion. Some of the specific activities this quarter are as follows: characterization tests were performed on three waste products from the General Atomics Plant of TVA; hydration reaction studies, compressive strength evaluations, and chemical analysis comparisons were conducted on samples of alliance atmospheric fluidized bed (AFB) residue obtained from the surface of stock piles in Canton, Ohio; varying amounts of water were added to various masses of AFB residue and the temperature rise versus time was monitored, and the final moisture content of the residue was monitored; additional evaluations were made of the properties of road base mixes made from stored mixtures of AFB residue and pulverized coal fly ash; laboratory scale production of synthetic aggregate by extrusion has been successfully accomplished at two locations; the use of a number of additional additives for improving the green strength of briquetted and extruded products has been explored; the modules of elasticity of hardened road base compositions has been determined.
