RSTQRMDIATIOH OBJECTIVES ELIMINATE ASBESTOS. KAINTAIN PRESENT YIELD, RAW MATERIAL COST, AND PHYSICAL PROPERTIES. OBTAIN UNDERWRITERS LABORATORIES LABEL SER VICE ON NEW COMPOSITION IN REGARDS TO FORMDLATION, APPLICATION, SURFACE FLAMMABILITY, THERMAL INSULATION AND EON*D TO STEEL. PROGRESS TO DATE THROUGH A SERIES OP OVER 50 PILOT FIRE TESTS INVOLVING FORMULATION, APPLICATION, CURING, COSTING AN D EXPOSURE TO ASTM E-119 TIME-TEMPERATURE CURVE, WE HAVE: 1 ' * RESEARCH " DEFINED FUNCTION OF ASBESTOS, AS A WATER ADSORBANT TO IMPROVE YIELD, AND TO REDUCE PUMPING PRESSURES. DETERMINED THAT ORGANIC AGENTS KAY B E SUBSTITUTED. RULED OUT CERAMIC, MINERAL AND GLASS FIBERS BECAUSE OF COST, UNADAPTABILITY OR AS CONSTITUTING HEALTH HAZARDS. RULED OUT MINERAL FILLERS AS CLAYS, BENTONITES, DIATOKACEOUS EARTH, EXPANDED PERLITE AND COATED ASBESTOS BECAUSE OF POOR YIELD .AND-BOND, OR OF EXCESSIVE ABRASION TO MIXERS A!ID FVMPS. PROGRESS TO DATE (contd) SELECTED CELLULOSE SULFITE PULP AS AN ACCEPTABLE REPLACEMENT. ' . EXPERIENCED LIMITED SUCCESS KITH A GRANULAR WATER SOLUBLE CELLULOSE (METKOCEL K.G. ). . OBSERVED THE EFFICIENCY OF DAXAD 30 IN ELIMINATING CRACKING TENDENCIES OF MONO-KOTE DURING EXPOSURE TO FIRE TEST. ' EXPLORED FUNCTION OF VARIOUS AGGREGATE SIZES. EXPLORED WATER REQUIREMENT VERSUS YIELD ON SELECTED COMPOSITIONS.
