12、e requirements forfloor surfacing products. When specifying surfacing overconcrete according to this standard, the floor surfacing shall beclassified by the application method, resin chemistry, aggregatetype, and applied thickness.4.2 The specifier must consider service conditions such aschemical ex
13、posure, traffic, and temperature conditions in se-lecting the flooring system.1This specification is under the jurisdiction of ASTM Committee C03 onChemical-Resistant Nonmetallic Materials and is the direct responsibility ofSubcommittee C03.02 on Mortar and Monolithics.Current edition approved March

16、the concrete, concrete surface preparation, surfac-ing installation, and finished floor slope and surface texture.4.4 Additional items that may be required for specificapplications but are not specified in this standard include floorsurfacing electrical conductivity, spark generation properties,and
17、flatness and levelness.5. Classification5.1 Classification by application method includes: troweled(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
18、 (VE).6. Materials6.1 Most of these systems include three components: aresinous liquid, a liquid setting agent, and an aggregatecomponent.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), iso
19、cyanates (for urethanes), and peroxides (forpolyesters and vinyl esters).6.4 The aggregates or fillers are usually siliceous or carbon-aceous materials. These materials are selected to have adequateresistance to the chemicals that are in the area where they areinstalled and are properly sized to pro
20、vide ease of application.6.4.1 Other aggregates and/or filler components are fre-quently used to obtain specific properties. Aluminum oxide andsilicon carbide are used to provide increased abrasion and/orslip resistance properties in the flooring system.6.5 Reinforcing materials used with these floo
21、ring systemsmust themselves be chemical resistant. Such materials includesynthetic, carbon or fiberglass materials in mats, strands orrovings.6.6 The surfacing materials for TR, SL and SP systems areusually installed by mixing the resin with the setting agent,blending in the aggregate component unti
22、l uniform and ho-mogenous, and then placing and finishing the mixture onto aproperly prepared concrete substrate as per Practice C 811.6.7 The surfacing materials for BC systems are usuallyinstalled by mixing the resin with the setting agent (calledliquids here), and then spreading onto a properly p
23、reparedconcrete substrate. This is followed by broadcasting the aggre-gate to excess into the wet film. The application is allowed toharden. The excess aggregate is removed. The surface is thentopcoated with the same liquids or the application process isrepeated until the desired thickness is reache
24、d, and then thesurface is topcoated.6.8 In a SBC system, the resin, setting agent and aggregateare blended and applied on a properly prepared concretesubstrate. More aggregate is then broadcast into this slurry andallowed to harden. The excess aggregate is removed and thesystem is then topcoated.6.9
25、 RF systems are usually applied as the TR, SL or SPsystems. The reinforcement is usually embedded in this layerand then the reinforcement is saturated with liquids. A secondTR, SL, or SP layer is then applied.6.10 The components of the floor surfacing systems areusually formulated to perform optimal
26、ly at specified mixingratios. They are usually either packaged by the manufacturer inthe required proportions (weight or volume) or mixing instruc-tions include guidelines for mixing proportions.6.11 Any of these systems may be topcoated. At therecommendation of the manufacturer of the system, thist
27、opcoat may be mandatory for optimal appearance and perfor-mance.6.12 Many floor surfacings include some type of finishtexture or profile incorporated into the design of the surfacethat can range from relatively smooth to extremely aggressive.TR systems without a sealing topcoat, BC and SBC systemsin
28、herently produce surfaces with a texture. SL systems usuallyproduce a smooth surface. Other common methods for incor-porating texture include: broadcasting an aggregate into atopcoat (and optionally, resealing); or mixing an aggregatedirectly into the topcoat before application.6.13 Occasionally, fl
29、oor surfacings are required to havespecific conductive or static dissipative electrical properties forpersonnel or product protection. Specific requirements forelectrical resistance are not covered in this standard. Refer toESD-S7.1 for test methods to determine this property.6.14 In areas where fla
30、mmable materials are present, it maybe required that floor surfacings be non-sparking when im-pacted with metallic or other hard materials. Specific require-ments for non-sparking properties are not covered in thisstandard.7. Physical Properties, Chemical Resistance andPerformance Requirements7.1 Re
