A. Doyle, the possibility of the Washington Research Center (WRC) conducting research on the Wellman-Power Gas SO2 recovery system was discussed with Wellman representatives. They are meeting considerable success in commercializing their sodium sulfite SO2 recovery system but are in need of data and information concerning the effect of certain sulfur and nitrogen compounds on the chemistry of their process. The required data are not available in the literature and Wellman is not equipped with laboratory facilities for this type of activity. In view of the close association which ACG has with Wellman, we have been asked to determine the basis upon which we would gather the desired information. Basically, the work would be divided into three phases. Phase I would be a study of the static system chemistry; Phase II, a study of the dynamic system chemistry; and Phase III, which would be considered later, would be a study of anti oxidants in the dynamic system. Time and costs for conducting this research has been estimated to be as follows: Phase I Phase II TOTAL 8 weeks 10 weeks 18 weeks - $16,000 - $20,000 - $36,000 These cost estimates have been forwarded to Mr. Gerald Smith, Wellman-Power Gas, along with details of the proposed program as outlined by Wellman. We will await their reply and authorisation of funds before proceeding on this project. (Legal, Kraus, Kolbe) A-2 FORMULATION AND EVALUATION OF M0N0-K0TE (Project 2659) CPD is encountering marketing problems with their MK-3 and MK-4 Mono-Kote, fireproofing materials. Asbestos, which is used in the MK-3 formulation is a suspected health hazard. and steps have been taken in some areas to prohibit its use in fireproofing formulations. Mk-4, which does not contain asbestos, is inferior to MK-3 because of its poor fire rating. To date, attempts to develop suitable replacements for MK-3 and MK-4 have been unsuccessful, based on Underwriters Laboratories1 type test for flat deck panels. Accordingly, a recent decision was made by CPD to shift the immediate objective of the project. Al though the basic objective of developing an asbestos-free 15208315 I I CONSOLIDATED EDITION October 12, 1971 Mono-Kote with 100% total equivalency to MK-3 remains the same, an attempt now is being made to pass UL type tests with a blend deck rather chan a fiat deck. A blend deck is a combination" of corrugated and fiat deck and accounts for the greater portion of the commercial market. January, 1972, has been set as a goal for attainment of a commercial non-asbestos product meet ing UL requirements on a blend deck. Laboratory work has shown Mono-Kote properties can be changed drastically by the addition of certain types of chemi cals. Several formulations developed both at WRC and Traveler's Rest show promise of success. Larger scale fire tests of promis ing formulations are underway at Ohio State University and U. S. Gypsum Laboratories, Chicago, Illinois. These decks are all blend construction, which CPD plans to start fire testing in September and will continue into October. ' Seven compositions, derived from the last several months of research at WRC, appear promising based on lab test data. The best result (performance score of 69) was obtained with a composition containing 6% Cement "C" and 1% fiberglass. This compares favorably to a performance score of 50 for MK-3 and 25 for MK-4. Mono-Kote formulations containing portland cement, substituted for gypsum, gave relatively poor performance scores (for the most part R30) and, at this point, appear inferior to gypsum base formulations. However, work with the portland cement system is to continue, at CPD's request, until a better under standing of the relationship between bond performance and the fire endurance tests is gained. Results of recent data will be reviewed with CPD at Cambiiuge on September 27, 1971. Samples of material used to prepare larger scale tests will be tested and rated at WRC to determine the meaning or import of the WRC performance score compared with the fire endurance rating of the larger scale tests. (Kraus, Legal) A-3 SILICATE CONSTRUCTION MATERIALS (Project 2662) All test compositions in the sodium silicate-sodium silico-fluoride experimental plan have been prepared and par tially evaluated. New data obtained during this report period show that (1) low values in the fire cup test generally coincide with greater than 4% shrinkage during curing and (2) 57 fiberglass or de-oiled mineral wool added to a low water formulation im proves the compressive and tensile strengths. The strength improvement with fiberglass is slightly greater than with mineral wool but costs about 10% more for equal coverage. 15208316 i
