8、ent terrazzo where the light weight of the thin set system would be advantageous.The conductive resinous terrazzo flooring is primarily intended for use in areas where volatile materials are handled, clean-rooms, parachute assembly areas, etc. These systems, which have a wear factor four times bette
9、r than cementitious terrazzo and five to six times better than vinyl may be used, when economically justified, in hard wear areas where there is a need for a high degree of cleanliness, a decorative effect, and some chemical resistance. These systems will not be used over SECTION 09 66 23 Page 2Prov
10、ided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-lightweight concrete and will not be used in lieu of quarry tile in kitchens.The selection of a floor system for a location where resistance to specific conditions is important should be based upon the abil
11、ity of the system to withstand required exposure conditions. For example, polyesters are suitable where resistance to detergents is required but should not be used in laboratory or other areas where spillage of sodium hydroxide or similar strong alkaline solution occurs; epoxies should not be used w
12、here resistance to oxidizing acids is required or where resistance to temperatures in excess of 54 degrees C (130 degrees F) is required; latex mastic and resin emulsions should not be used where resistance to strong acids or alkalis is required. Each job should be evaluated on its own merits consid
13、ering exposure conditions, costs, and local experience with the various systems.Areas to receive terrazzo will be shown on the drawings. Color should be shown by specifying a selected plate number from the NTMA publication, “Terrazzo Information Guide.“ Example: NTMA terrazzo catalog, plate No. S-30
14、1-4. Colors selected may be any combination of standard marble granules of domestic origin available in the local market, but it is highly desirable that color combinations be designated by NTMA color plates.*1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of t
