Terminology3.1 Definitions3.1.1 For definitions of terms used in this specification, referto Terminology C 125.3.2 Definitions of Terms Specific to This Standard:3.2.1 manufacturer, nthe producer who furnishes thefiber-reinforced concrete.3.2.2 purchaser, nthe owner, or representative

21、 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 the fibers to physical damage during mixing

22、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 of fiber; consultmanufacturer for advice as

23、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 ConcreteContainsstainless steel, alloy steel

24、, or carbon steel fibers conforming toSpecification A 820/A 820M.4.1.2 Type II Glass Fiber-Reinforced ConcreteContainsalkali-resistant (AR) glass fibers conforming to SpecificationC 1666/C 1666M.4.1.3 Type III Synthetic Fiber-Reinforced ConcreteContains synthetic fibers for which documentary evidenc

25、e 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 such as polyolefins (polypropylene and p

26、olyethylene),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 moisture and alkalis present in cement pa

27、steand 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 D 7357.NOTE 3The classification, natural fibers, refers to a population offibers that are manufactur

28、ed 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 vary greatly.Some natural fibers are susc

29、eptible to deterioration from exposure toalkalis; Test Method D 6942 may be used to determine the susceptibilityof these fibers to deterioration as a result of exposure to alkalis in concrete.Conversely, many other natural fiber types are highly resistant to alkalisand can remain in concrete with no

30、 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 fiber proposed for use showsresistance t

33、rchasers option, otherwisethe cement shall be Type 1 meeting the requirements ofSpecification C 150;6.1.3 Designated size, or sizes, of coarse aggregates;6.1.4 Slump required at the point of delivery, or whenappropriate the point of placement, subject to the toleranceshereinafter specified;6.1.5 Air

34、 content when air-entrainment is required, based onthe air content of samples taken at the point of discharge, orwhen appropriate the point of placement, subject to thetolerances hereinafter specified;NOTE 4In selecting the specified air content, the purchaser should3Available from American Concrete

Box 9094, FarmingtonHills, MI 48333-9094, http:/www.aci-int.org.C 1116/C 1116M 092consider the exposure conditions to which the concrete will be subjected.Air contents less than shown in Table 1 may not produce adequatedurability. Air contents higher than the levels shown may

36、reduce strengthwithout contributing further to freeze-thaw resistance.6.1.6 When structural lightweight concrete is specified, thepurchaser shall specify the density as freshly mixed density,equilibrium density, or oven-dry density.NOTE 5The freshly mixed density of lightweight concrete, that is the

37、only density determinable at the time of delivery, is always higher than theequilibrium density or oven-dry density. Definitions of, and methods fordetermining or calculating freshly mixed, equilibrium, and oven-drydensities of lightweight concrete are covered in Test Methods C 138/C 138M and C 567.

38、6.1.7 If desired, any of the optional requirements of Table 2of Specification C 1602/C 1602M.6.1.8 One of the following Options A, B, or C, shall be usedas the basis for determining the proportions of the fiber-reinforced concrete of the quality required.6.2 Option A:6.2.1 When the purchaser assumes

39、 responsibility for mix-ture proportioning, the following parameters shall also bespecified by the purchaser:6.2.1.1 The cement content in kilograms per cubic metrepounds per cubic yard,6.2.1.2 If supplementary cementitious materials are re-quired, the type, and amounts to be used in kilograms per c

41、 required, the type,name, and dosage range to be used to achieve the specified aircontent, (see 6.1.4),6.2.1.5 If chemical admixtures are required, the type, name,and dosage range to be used, and:6.2.1.6 The type of fibers to be used and the amount inkilograms per cubic metre pounds per cubic yard,

42、(seeClassification Section 4).NOTE 6The dosage of air-entraining, water-reducing (including high-range), accelerating, and retarding admixtures needed to satisfy thematerial performance requirements varies. Therefore, dosage rangesshould be specified to ensure that the material performance requireme

43、ntscan be met.NOTE 7The purchaser, in selecting requirements for which he as-sumes responsibility should give consideration to requirements for work-ability, placeability, durability, surface texture, and density. The purchaseris referred to ACI Practices 211.1 and 211.2 for selecting proportions th

44、atwill result in concrete suitable for various types of structures andconditions of exposure, and to ACI Report 544.3R4for selecting concreteand fiber parameters suitable for fiber-reinforced concrete. For guidanceon selecting proportions for fiber-reinforced shotcrete, the purchaser isreferred to A

45、CI Reports 506.1R5and 506.R6and ACI Specification 506.2.6.2.2 At the request of the purchaser, the manufacturer shall,prior to the actual delivery of concrete, furnish a statement tothe purchaser giving the sources, relative densities, sieveanalyses, and saturated surface-dry masses of fine and coar

46、seaggregates, and the amount of mixing water per cubic metreper cubic yard that will be used in the manufacture of eachclass of concrete ordered by the purchaser.6.3 Option B:6.3.1 When the purchaser requires the manufacturer toassume full responsibility for mixture proportioning (see Note7), the pu

47、rchaser shall also specify the following:6.3.1.1 Requirements for flexural performance determinedin accordance with one of the following: Test Method C 1399,C 1550 or C 1609/C 1609M, using samples obtained at thepoint of discharge, or when appropriate at the point ofplacement. At the option of the p

48、urchaser, compressivestrength (Test Method C 39/C 39M) shall be specified when theflexural requirements are considered inadequate for ensuringthe quality of the matrix of the fiber-reinforced concrete.Unless accelerated curing and testing in accordance with thewarm water or boiling water procedures

49、of Test Method C 684is specified, tests shall be performed after standard moistcuring in accordance with Practices C 31/C 31M at 28 days, orsuch other ages as are specified by the purchaser.NOTE 8While flexural strength at first peak is affected by the type andamount of fibers, it is more dependent on the characteristics of the mortaror concrete matrix, so it is recommended that the purchaser, whenspecifying flexural strength at first peak, consider factors known toinfluence the strength of normal concrete such as, water-cement ratio,aggregate maximum size,
