Abstract
A building material consists essentially of an aqueous slurry of a dry residue obtained by treating a flue gas containing fly ash from a fossil fuel combustion chamber with a finely divided absorbent consisting at least primarily of calcium oxide, calcium hydroxide and calcium carbonate to permit reaction between the absorbent and sulfur dioxide in the flue gas, and dry separation of the reacted absorbent from the residual flue gas.
