摘要

The residue from the Ames Lime-Soda Sinter Process for recovering alumina from power plant fly ash consists largely of dicalcium silicate and shows promise as a raw material for the manufacture of a low-alumina, sulfate-resistant portland cement. A laboratory burnability study has been conducted to determine the best way to utilize this raw material from both clinker quality and economic perspectives. These tests are essential when a new material, such as the lime-sinter process residue, it to be considered as a possible cement raw material. The amount of unreacted lime can be used as a measure of the reactivity of a raw mix by indicating the extent to which the cement reactions have progressed. Conditions of residence time and temperature used for the burnability tests were chosen to simulate actual kiln operation. A factorial experimental design made of the parameters of burning temperature, lime content, and lumina (flux) content. Preliminary results from this study indicate that a raw mix made from the sinter residue yields a satisfactory cement. (ERA citation 11:036185)
