C. Spent ion exchange resins (nos. 12 and 14) will be processed with
cement after a pretreatment process wherein the resin beads or granules
are destroyed. A chop blending method will be used for slurries or wet
resin, and milling will be used for dry resin.

properties and the flock is too basic for materials such as sulfur
polymer cement. The use of trade mark Aquaset or Petroset from Fluid
Tech, Inc. could be lab tested for this application.
E' , The ash residue (no. 15) as well as the basin'grit (no. 10) would best
be used as blending agents to stretch the cement and improve its
strength and containment characteristics. It will be tested in this
__manner._Ash_i.s_a good candidate for sulfur polymer cement, but this
would require a different type of facility equipment. An effort will
be made-to prouide-some- i-nformation-on the use of sulfur polymer cement
for ash immobilization. There are other miscellaneous wastes that
would probably be immobilized better in sulfur polymer cement than the
other cements.
Work on these waste immobilization methods will begin in the laboratory
within the next week with the intent to show that they meet present and
anticipated future waste disposal criteria.
