also be examined for unacceotable flammability or combustibility
characteristics. The other class of solidifiers is inorganic binders which
offer some of the characteristics of both cementitious agents and organic
binders.
The most useful literature packet is one entitled "Literature Search for
WRAP Solidifiers." It summarizes most of the important references. The
literature pointed out a number of additives or modifiers that improve waste
product performance particularly for cement. Materials such as lime,
silica, or alumina can improve cement leachability. For gypsum cements,
retardant modifiers are probably necessary for proper solidification of
phscerxfoarisand Envirostane*was*.e products' A1so, materials or
reagents to avoid are important in considering the use of organic binders or
polymers. A number of these guidelines are included in the literature
references and summaries.
This completes the initial phase of the WRAP literature search. We will
attempi to keep the iiterature search current with time and periodically
update to support the design work. If you have any questions or comments,
please call me on 6-9616.

submitted a procurement request to obtain some for laboratory testing and
evaluation.
