Book excerpt: The following conclusions are recorded: The road base mixes in which quartz silica was substituted for the pulverized coal fly ash gave compressive strengths similar to those using the pulverized coal fly ash. The compressive strengths of road base mixes using recently produced AFB residue were of the same order of magnitude as those obtained in 1977, although the data covers a broad range of test results. Briquettes, produced from a number of trial mixes, show promise as a synthetic aggregate. Expansive grout mixes of slurry consistency achieve satisfactory compressive strengths in seven days. Sections of the test strips in Canton, Ohio show minimal expansion.

Book excerpt: An AFB fly ash sample from Georgetown University shows a significant difference in visual appearance to that of other AFB fly ash sources. Differences in the chemical composition of spent bed residue samples from Rivesville, West Virginia, are probably attributable to variations in the calcium to sulfur ratio in the fluidized-bed during combustion. Comparison of the particle size distribution of spent bed samples from Alliance, Ohio, and Georgetown University reveals a close similarity in the basic sizing of these materials, with each being considered in the medium to coarse sand size range. Visual inspection of the separated overflow sample from mineral cyclone separation indicates that this product may contain a relatively high percentage of lime. On the basis of available data, it appears that detrimental volume expansion in road base compositions containing AFB residue can be reduced to a tolerable level by pre-treatment, such as grinding and/or maximum hydration prior to use. Additions of relatively low percentages of AFB residue to acid mine waste-water resulted in significant increases in the percentage of solids of vacuum filtered samples, due to the low solids content of the wastewater sample. The addition of AFB residue to acid mine wastewater is effective in neutralizing the pH and dewatering the waste, although previous neutralization tests have shown that milled AFB residue is generally more reactive and effective than as received AFB residue. Combinations of equal weights of AFB residue and fly ash appear to produce relatively high strength block. Blocks with 80 percent AFB residue and 20 percent fly ash exhibited somewhat lower strengths with little or no cracking.

Book excerpt: The free lime content of the spent bed residue sample from the Georgetown AFB boiler has higher than average free lime, total lime, and magnesium content, and smaller than normal proportion of silica, aluminum, and iron, when compared to previously analyzed spent bed residue samples from other sources. Investigation of the use of spent bed residue as a component of blended cement revealed expansive properties which make such use for conventional concrete construction purposes somewhat questionable. However, these blended cement mixes expand in a predictable manner, show no cracking, and do increase in strength over time, suggesting their application as an expansive concrete for pressure grouting and stowage for mine backfilling. AFB residue/fly ash blends mixed with clay-silt soil exhibit strength development and volume stability characteristics that further recommend the application of such blends as a soil grouting medium. The information and experience obtained in the masonry block demonstration permit an accurate design of mix formulations using AFB residue with conventional block making equipment to meet current ASTM specifications for masonry block. Pre-treatment is necessary in order to develop high-carbon AFB fly ash for use in water treatment applications.

Book excerpt: Oils and Gases from Coal reviews the state-of-the-art in oil and gases from coal in Europe and North America based on the work of the Symposium on the Gasification and Liquefaction of Coal. The said symposium is held under the auspices of the United Nations Economic Commission for Europe at Katowice, Poland on April 23-27, 1979. Separating 23 papers as chapters, this book begins with the opening lecture on the efficiency of coal gasification and liquefaction processes. Other papers focus on the assessment of world resources of coal and prospects for the production of different types of coal; comparative end-use efficiency of the use of coal; theoretical bases of coal gasification; underground coal gasification; and use of coal products for non-energy purposes. The utilization or disposal of coal processing residues; development of processes of semi-coking and gasification of oil shales; further development of Fischer-Tropsch synthesis; application of fluidization in coal gasification; and evaluation of the trade-offs from regional coal development and environmental strategies are also explained.
