Terminology3.1 Definitions:For definitions of terms used in this standard, see Terminology C904.3.1 DefinitionsFor definitions of terms used in this standard, see Terminology C904.4. Significance and Use4.1 This standard specification covers the requirements for flo

20、or surfacing products. When specifying surfacing over concreteaccording to this standard, the floor surfacing shall be classified by the application method, resin chemistry, aggregate type, andapplied thickness.4.2 The specifier must consider service conditions such as chemical exposure, traffic, an

21、d temperature conditions in selectingthe flooring system.4.3 Other items that are not specified in this standard but are important to the performance of the floor surfacing includecondition of the concrete, concrete surface preparation, surfacing installation, and finished floor slope and surface te

22、xture.4.4 Additional items that may be required for specific applications but are not specified in this standard include floor surfacingflammability, electrical conductivity, spark generation properties, and flatness and levelness.5. Classification5.1 Classification by application method includes: t

23、roweled (TR), broadcast (BC), slurry broadcast (SBC), self-leveling (SL),spray (SP), and reinforced (RF).5.2 Classification by resin chemistry includes epoxy (EP), urethane (UR), polyester (PE), and vinyl ester (VE).6. Materials6.1 Most of these systems include three components: a resinous liquid, a

24、 liquid setting agent, and an aggregate component.6.2 The resinous liquid shall be epoxy, urethane (polyol), polyester or vinyl ester.6.3 The setting agents for these materials are usually amines (for epoxies), isocyanates (for urethanes), and peroxides (forpolyesters and vinyl esters).6.4 The aggre

25、gates or fillers are usually siliceous or carbonaceous materials. These materials are selected to have adequateresistance to the chemicals that are in the area where they are installed and are properly sized to provide ease of application.6.4.1 Other aggregates and/or filler components are frequentl

26、y used to obtain specific properties. Aluminum oxide and siliconcarbide are used to provide increased abrasion and/or slip resistance properties in the flooring system.6.5 Reinforcing materials used with these flooring systems must themselves be chemical resistant. Such materials includesynthetic, c

27、arbon or fiberglass materials in mats, strands or rovings.6.6 The surfacing materials for TR, SL and SP systems are usually installed by mixing the resin with the setting agent, blendingin the aggregate component until uniform and homogenous, and then placing and finishing the mixture onto a properl

28、y preparedconcrete substrate as per Practicein accordance with C811. NACE#6/SSPC-SP13.6.7 The surfacing materials for BC systems are usually installed by mixing the resin with the setting agent (called liquids here),and then spreading onto a properly prepared concrete substrate. This is followed by

29、broadcasting the aggregate to excess into thewet film. The application is allowed to harden. The excess aggregate is removed. The surface is then topcoated with the sameliquids or the application process is repeated until the desired thickness is reached, and then the surface is topcoated.3 The last

31、org.C722 1826.8 In a SBC system, the resin, setting agent and aggregate are blended and applied on a properly prepared concrete substrate.More aggregate is then broadcast into this slurry and allowed to harden. The excess aggregate is removed and the system is thentopcoated.6.9 RF systems are usuall

32、y applied as the TR, SL or SP systems. The reinforcement is usually embedded in this layer and thenthe reinforcement is saturated with liquids. A second TR, SL, or SP layer is then applied.6.10 The components of the floor surfacing systems are usually formulated to perform optimally at specified mix

33、ing ratios.Theyare usually either packaged by the manufacturer in the required proportions (weight or volume) or mixing instructions includeguidelines for mixing proportions.6.11 Any of these systems may be topcoated. At the recommendation of the manufacturer of the system, this topcoat may bemandat

34、ory for optimal appearance and performance.6.12 Many floor surfacings include some type of finish texture or profile incorporated into the design of the surface that canrange from relatively smooth to extremely aggressive. TR systems without a sealing topcoat, BC and SBC systems inherentlyproduce su

35、rfaces with a texture. SL systems usually produce a smooth surface. Other common methods for incorporating textureinclude: broadcasting an aggregate into a topcoat (and optionally, resealing); or mixing an aggregate directly into the topcoat beforeapplication.6.13 Occasionally, floor surfacings are

36、required to have specific conductive or static dissipative electrical properties forpersonnel or product protection. Specific requirements for electrical resistance are not covered in this standard. Refer to ESD-S7.1for test methods to determine this property.6.14 In areas where flammable materials

37、are present, it may be required that floor surfacings be non-sparking when impactedwith metallic or other hard materials. Specific requirements for non-sparking properties are not covered in this standard.7. Physical Properties, Chemical Resistance and Performance Requirements7.1 Requirements for Tr
