A number in parentheses indicate

2、s the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers concrete drain tile with inter-nal diameters from 4 t

3、o 36 in. that are intended to be used forsurface and subsurface drainage.1.2 Acomplete metric companion to Specification C412 hasbeen developedC412M; therefore, no metric equivalents arepresented in this specification.NOTE 1This specification is a manufacturing and purchase specifica-tion only and d

4、oes not include requirements for bedding, backfill, or therelationship between field load condition and the strength classification ofdrain tile. However, experience has shown that the successful performanceof the product depends upon the proper selection of the class of drain tile,type of bedding a

5、nd backfill, and care that the installation conforms to theconstruction specifications. The owner is cautioned that he must correlatethe field requirements with the class of drain tile specified and provide foror require inspection at the construction site.2.

Chemical Requirements7.1 Acid and Sulfate Resistance:7.1.1 The owner is not prohibited from specifying specialrequirements in order to increase the durability of the drain tilein cases where the soils,

27、 soil waters, or drainage waters aremarkedly acid or contain moderate or severe quantities of soilsulfates. Without a specific agreement in advance, no drain tileshall be rejected by reason of its composition as determinedlater by chemical analyses.7.1.1.1 Soils or drainage waters with a pH of 6.0 o

29、to be severe sulfate quantities.7.1.2 Concrete drain tile that will be installed in markedlyacid soils shall meet the physical requirements given in thetable for Special-Quality concrete drain tile.7.1.3 Tile that will be exposed to moderate or severe sulfatequantities (Note 2) if if required by the

30、 owner, shall bespecified to meet the physical requirements for Special-Qualityconcrete drain tile (8.3.4). Tile that will be exposed to moderatesulfate quantities (Note 2), if required by the owner, shall bespecified to be made with Portland Cement (C150/C150M)containing not more than 8 % tricalciu

31、m aluminate (C3A). Tilethat will be exposed to severe sulfate quantities (Note 2), ifrequired by the owner, shall be specified to be made withPortland Cement (C150/C150M) containing not more than 5 %C3A. If mutually agreed upon between the manufacturer andowner, other cements, as described in Sectio

32、n 6, that have beenproven to be adequately sulfate resistant shall be used.8. Physical Requirements8.1 Test SpecimensThe drain tile to be tested shall beselected at random by the owner at the point or points specifiedin the order. If agreeable to the owner, the tile shall beinspected and tested in a

33、dvance of shipment. Any additionalexpense for making tests and inspection in advance of ship-ment shall be paid by the manufacturer.8.2 Standard SampleEach standard physical test shall bemade on five individual tile of each size ranging from 4-in.through 12-in. diameters; two individual tiles of eac

34、h sizeranging from 14-in. through 24-in. diameters; or on one tile ofeach size exceeding 24 in. in diameter. The manufacturer shallfurnish tile without separate charge up to 0.5 % of each size ofthe order. The owner shall pay for all the tile in excess of 0.5 %of each size of the order at the same p

35、rice as paid for other tileof the same size and quality.8.3 External Load Crushing Strength Test Requirements:C412 1528.3.1 For Standard-Quality concrete drain tile, the three-edge-bearing crushing strength shall meet the requirementsgiven in Table 1, Column A, where no absorption test isrequired, o

36、r the three-edge-bearing crushing strength shallmeet the requirements given in Table 1, Column B, where anabsorption test is required of the limits noted in Table 1.8.3.2 For Extra-Quality concrete drain tile, the three-edge-bearing crushing strength shall meet the requirements given inTable 2, Colu

37、mn A, where no absorption test is required, or thethree-edge-bearing crushing strength shall meet the require-ments given in Table 2, Column B, where an absorption test isrequired of the limits noted in Table 2.8.3.3 For Heavy-Duty Extra-Quality concrete drain tile, thethree-edge-bearing crushing st

38、rength shall meet the require-ments given in Table 3.8.3.4 For Special-Quality concrete drain tile, the three-edge-bearing crushing strength shall meet the requirements given inTable 4, or the higher specified load.NOTE 2To meet the crushing strength requirements shown in thetables, it is not prohib

39、ited to supply tile designed with increased wallthickness, high compressive strength concrete, or reinforcing, or acombination.8.4 Absorption Tests:NOTE 3Method A absorption test is recommended for drain tilehaving diameters of 12 in. or less. When Method B absorption test is used,the absorption req

40、uirements shall be 0.5 % less than the Method Aabsorption requirements, as shown in Table 1, Table 2, Table 3,orTable4. Method B absorption procedure is described in Test Methods C497.8.4.1 For Standard-Quality concrete drain tile, the MethodA absorption test shall meet the requirements given in Tab

41、le 1.No absorption tests are required if the strength requirements ofTable 1, Column A, are met.8.4.2 For Extra-Quality concrete drain tile, the Method Aabsorption test shall meet the requirements given in Table 2.No absorption tests are required if the strength requirements ofTable 2, Column A, are

42、 met.8.4.3 For Heavy-Duty Extra-Quality concrete drain tile, theMethod A absorption test shall meet the requirements given inTable 3.8.4.4 For Special-Quality concrete drain tile the Method Aabsorption test shall meet the requirements given in Table 4.8.4.5 Specimens for the Method A absorption test

43、s shall beselected in accordance with the following provisions:8.4.5.1 For the tile with inside diameters of 12 in. or less,and lengths of 12 in., the absorption test shall be made on onefull-length quarter segment taken from each of the five tilebroken in the strength test, constituting a standard

44、sample asdefined in 8.2. By quarter segment is meant one of the fourpieces into which a tile usually breaks in the strength test. If atile breaks in such a manner that a satisfactory quarter segmentcannot be obtained, then the absorption test shall be made oftwo or more pieces that approximate the a

45、rea of a quarter tileof that size selected so that both ends and the center portion ofthe tile are represented. The average absorption of the pieces soselected shall be considered the absorption for that tile.8.4.5.2 For nonreinforced tile with inside diameters orlengths in excess of 12 in., the abs

46、orption test shall be made onthree specimens: one of the specimens shall be taken from oneend of the tile, another specimen from the opposite end, and thethird specimen from near the center. The average absorption ofthe three specimens shall be considered the absorption for thattile.8.4.5.3 For rein

47、forced tile, the absorption test shall be madeon one specimen taken from each test tile.8.4.5.4 The specimens shall be the full thickness of the tile,as broken or cut from segments that result from the strengthtest. Each specimen shall have a minimum area of not less than25 in.2as measured on one wa

48、ll surface.8.4.5.5 The average absorption for Standard-Quality, Extra-Quality, and Heavy-Duty Extra-Quality tile shall be the aver-age of the absorption tests for the standard sample as defined in8.2 or the average of the absorption tests for the strongest andthe weakest tile as measured by the crus

49、hing strength of thestandard sample. When drain tile fail to meet the absorptiontest requirement as computed by averaging the absorptionsfrom the weakest and the strongest tile of a standard sample,then the average absorption test shall be computed by averag-ing the absorption tests from all the tile from the standardTABLE 1 Physical Test Requirements for Standard-Quality Concrete Drain TileInternalDesignatedDiameter, in.Standard-Quality Concrete Drain TileMaximum WallThickness forIndicatedStrength,Ain.Three-Edge Bearing Crushing StrengthBMethod A AbsorptionMinimum
