21、.2.2 purchaser, nthe owner, or representative thereof,who buys the fiber-reinforced concrete.4. Classification4.1 This specification classifies fiber-reinforced concrete bythe material type of the fiber incorporated.NOTE 1The performance of fiber-reinforced concrete depends uponthe susceptibility of

22、 the fibers to physical damage during mixing orshotcreting and to chemical damage on exposure to the cement pastesolution, which is highly alkaline and may also contain carbon dioxide,chlorides, sulfates or oxygen. Improper methods of fiber addition to aconcrete mix can lead to balling of some types

23、 of fiber; consultmanufacturer for advice as to correct method before use. The magnitudeof improvements in the mechanical properties of the concrete or shotcreteimparted by fibers can also reflect the material characteristics, geometry,and design of the fiber type.4.1.1 Type I Steel Fiber-Reinforced

24、 ConcreteContainsstainless steel, alloy steel, or carbon steel fibers conforming toSpecification A820/A820M.4.1.2 Type II Glass Fiber-Reinforced ConcreteContainsalkali-resistant (AR) glass fibers conforming to SpecificationC1666/C1666M.4.1.3 Type III Synthetic Fiber-Reinforced ConcreteContains synth

25、etic fibers for which documentary evidence canbe produced confirming their resistance to deterioration whenin contact with the moisture and alkalis present in cement pasteand the substances present in admixtures throughout theanticipated useful life of the structure (see Note 2 and 4.2).NOTE 2Fibers

26、 such as polyolefins (polypropylene and polyethylene),nylon, and carbon have been shown to be durable in concrete.4.1.4 Type IV Natural Fiber-Reinforced ConcreteContains natural fibers for which documentary evidence can beproduced confirming their resistance to deterioration when incontact with the

27、moisture and alkalis present in cement pasteand the substances present in admixtures throughout theanticipated useful life of the structure. When Type IV fiber-reinforced concrete contains cellulose fibers they shall conformto Specification D7357.NOTE 3The classification, natural fibers, refers to a

28、 population offibers that are manufactured from natural fibrous resources and are usedfor the first time in concrete. Depending on the initial raw material and themanufacturing process employed to produce the fiber, the final physicaland chemical fiber properties in this general classification can v

29、ary greatly.Some natural fibers are susceptible to deterioration from exposure toalkalis; Test Method D6942 may be used to determine the susceptibility ofthese fibers to deterioration as a result of exposure to alkalis in concrete.Conversely, many other natural fiber types are highly resistant to al

30、kalisand can remain in concrete with no degradation for the complete productlife cycle.4.2 When the purchaser chooses to permit the use of fibersother than those complying with the classifications in 4.1, themanufacturer or supplier shall show evidence satisfactory tothe purchaser that the type of f

31、iber proposed for use showsresistance to deterioration when in contact with the moistureand alkalis present in cement paste and the substances presentin admixtures throughout the anticipated useful life of thestructure.5.
