21、 who furnishes thefiber-reinforced concrete.3.2.2 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-reinforc
22、ed concrete depends uponthe susceptibility of 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 ac
23、oncrete mix can lead to balling of some types 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 f

26、e structure (see Note 2 and 4.2).When Type III fiber-reinforced concrete contains polyolefinfibers, they shall conform to Specification D7508/D7508M.NOTE 2Fibers such as polyolefins (polypropylene and polyethylene),nylon, and carbon have been shown to be durable in concrete.4.1.4 Type IV Natural Fib
27、er-Reinforced ConcreteContainsnatural fibers for which documentary evidence can be producedconfirming their resistance to deterioration when in contactwith the moisture and alkalis present in cement paste and thesubstances present in admixtures throughout the anticipateduseful life of the structure.
28、 When Type IV fiber-reinforcedconcrete contains cellulose fibers they shall conform to Speci-fication D7357.NOTE 3The classification, natural fibers, refers to a population offibers that are manufactured from natural fibrous resources and are usedfor the first time in concrete. Depending on the init
29、ial 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 susceptible to deterioration from exposure toalkalis; Test Method D6942 may be used to determine the su
30、sceptibility ofthese 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 degradation for the complete productlife cycle.4.2 When the purchaser chooses to permit the use of
31、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 to deterioration when in contact with the moistureand alkalis present in cement paste and the substan

35、ranceshereinafter specified;6.1.5 Air 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 sh
36、ouldconsider 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 reduce strengthwithout contributing further to freeze-thaw resistance.6.1.6 When structural lightweig

38、en-dry density. Definitions of, and methods fordetermining or calculating freshly mixed, equilibrium, and oven-drydensities of lightweight concrete are covered in Test Methods C138/C138M and C567.6.1.7 If desired, any of the optional requirements of Table 2of Specification C1602/C1602M.6.1.8 One of
39、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 responsibility for mix-ture proportioning, the following parameters shall also bespecified by the purchas

Therefore, dosage rangesshould be specified to ensure that the material performance requirementscan be met.NOTE 7The purchaser, in selecting requirements for which heassumes responsibility should give
44、consideration to requirements forworkability, placeability, durability, surface texture, and density. Thepurchaser is referred to ACI Practices 211.1 and 211.2 for selectingproportions that will result in concrete suitable for various types ofstructures and conditions of exposure, and to ACI Report
45、544.3R5forselecting concrete and fiber parameters suitable for fiber-reinforcedconcrete. For guidance on selecting proportions for fiber-reinforcedshotcrete, the purchaser is referred to ACI Reports 506.1R6and 506.R7and ACI Specification 506.2.6.2.2 At the request of the purchaser, the manufacturer
46、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 coarseaggregates, and the amount of mixing water per cubic metreper cubic yard that will be used in the manufacture
47、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 purchaser shall also specify the following:6.3.1.1 Requirements for flexural performance determinedin accordance w
48、ith one of the following: Test Method C1399,C1550 or C1609/C1609M, using samples obtained at the pointof discharge, or when appropriate at the point of placement. Atthe option of the purchaser, compressive strength (Test MethodC39/C39M) shall be specified when the flexural requirementsare considered
49、 inadequate for ensuring the quality of the matrixof the fiber-reinforced concrete. Unless accelerated curing andtesting in accordance with the warm water or boiling waterprocedures of Test Method C684 is specified, tests shall beperformed after standard moist curing in accordance withPractices C31/C31M at 28 days, or such other ages as arespecified 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
