Manufacture8.1 ConcreteThe aggregates shall be sized, graded, pro-portioned, and mixed with cementitious material and water andadmixtures, if any, to produce a homogeneous concrete mixtureof such quality that the pipe will conform t

28、o the designrequirements of this specification. The water-cementitiousmaterial ratio of all concrete shall be 0.53, or less, by weight.Minimum concrete strength shall be 27.6 MPa.8.2 FinishPipe shall be substantially free of fractures,large or deep cracks, and surface roughness. The ends of thepipe

29、shall be normal to walls and center line of the pipe, withinthe limits of variations given in Section 15.9. Circumferential Reinforcement9.1 A line of circumferential reinforcement for any giventotal area may be composed of up to two layers for pipe withwall thicknesses of less than 180 mm or three

30、layers for pipewith wall thickness of 180 mm or greater. The layers shall notbe separated by more than the thickness of one longitudinalplus 6 mm. The multiple layers shall be fastened together toform a single cage. If the multiple layers of a cage containcircumferential splices, the individual laye

31、rs shall be rotated sothat the splices are staggered. All other specification require-ments, such as laps, welds, tolerances of placement in the wallof the pipe, and so forth, shall apply to this method offabricating a line of reinforcement. The design shall be basedon the centroid of the layers.9.2

32、 Reinforcement placement and concrete cover shall con-form to the approved manufacturing data. The nominal con-crete cover over the circumferential reinforcement shall not beless than be 25 mm in pipe having a wall thickness of 63 mmor greater, and shall not be less than 19 mm in pipe having aC1417M

33、 112wall thickness of less than 63 mm. The location of thereinforcement shall be subject to the permissible variations indimensions given in Section 15. Requirements for placementand protective covering of the concrete from the inner or outersurface of the pipe do not apply to that portion of a cage

34、 thatis flared so as to extend into the bell or reduced in diameter soas to extend into the spigot.9.3 Where the wall reinforcement does not extend into thejoint area, the maximum longitudinal distance to the lastcircumferential from the inside shoulder of the bell or theshoulder of the spigot shall

35、 be 75 mm, except that if thisdistance exceeds one half of the wall thickness, the pipe wallshall contain at least a total reinforcement area of the minimumspecified area per linear metre times the laying length of thepipe section. The minimum cover on the last circumferentialnear the spigot shoulde
