    Abstract

    The term “lime” includes a wide variety of materials produced by calcining or burning limestone or dolostone and using the resulting material directly or adding water to form a hydrated lime. Lime and products containing lime have been widely employed in landfills. Examples of the use of lime in landfill covers (caps), wastes, and liners are presented. Lime can provide a valuable chemical barrier to the transport of specific contaminants. Lime-pozzolan cements can be used to improve handling of wastes and decrease waste compaction. Lime-soil mixtures can be employed as low-permeability, chemically reactive liners.

    Well-documented demonstration projects are required to obtain data needed for the acceptance of lime-augmented landfill designs. Where waste containing lime is employed, standards should be presented as to the chemical characteristics of waste that make them acceptable.
