    Abstract

    Aggregates can be produced from diverse waste materials such as fly ash, waste clay, foundry effluent, phosphate slime, and municipal refuse. Finely divided particulates are characterized for the ability to form an aggregate using either a rotary kiln or traveling grate sintering machine. If the material does not possess the required characteristics for making an artificial aggregate, various additives can be used to upgrade the processing parameters. Residues from incineration of municipal refuse can be used either upon separation and classification, or after incineration. Qualities for a good concrete aggregate are strength, particle shape to promote good workability, low water absorption, and chemical and physical stability.
