Abstract
Bench-scale experiments to examine methods for potential use of modified flyash indicate that this ash, the solid by-product resulting from the limestone/dolomite process for fixing gaseous sulfur oxides as solid sulfates, can be considered a suitable raw material for a number of new products and processes. The most promising methods of utilization incorporating the total use of modified flyash are the production of calcium-silicate and cement-like structural products, high temperature production of materials such as mineral wool insulation, and the use of modified flyash as a soil stabilizer and amendment. Other use areas were examined and are mentioned; also, several process problems and limitations are discussed. (Author)
