Coolside waste management research. Quarterly report, July 1, 1993--September 30, 1993
Monitoring of swell continued on Coolside pilot plant run {number_sign}2 and FBC ash remolded near 95% of standard maximum dry density and optimum moisture content. Swell test also continued on non-hydrated FBC specimens as well as FBC pellets which were loosely placed in CBR molds. No significant deviations from previously reported patterns have been observed. Field and laboratory leaching studies have shown that the Coolside materials display low initial permeabilities which rapidly decrease upon addition of water. Where leaching was occurred the leachates are initially very high in sodium and chloride ions (10,000`s ppM) potassium and sulphate (1,000`s ppM), with lesser concentrations of molybdenum, boron, aluminum (10`s ppM), arsenic, selenium and vanadium (ppM) being detected. In some cases concentrations were shown to rapidly decrease by an order of magnitude within a few pore volume changes.
