PART 2 - PRODUCTS

2.1   GENERAL

      A. Except as modified herein, reinforced concrete pipe shall conform to the
         requirements of ASTM Designation C 76 for Class [II,] Wall [B,] and Type II cement.
         Unless otherwise specified, pipe shall have tongue and groove joints designed to be
         self-centering and to leave a recess on the inside of the pipe for pointing with mortar
         after jointing. Pipe shall be designed for an internal pressure of [    ] feet of water,
         and an external load of [ ]-D.

      B. The size, type, and D-load of the concrete pipe to be furnished shall be as shown on
         the Drawings, as specified under the bid item of work for the project, or as stated
         above.

      C. When pipe joints of the reinforced concrete collar type or of rubber-gasketed type are
         specified or indicated on the Drawings, joint details shall be submitted to the
         ENGINEER for acceptance before commencing pipe manufacture.

2.2   MATERIALS

      A. Except when otherwise permitted by the ENGINEER, no materials shall be used in
         manufacturing of the pipe other than water, portland cement, mineral aggregates and
         steel conforming to ASTM C 76, with the following exceptions:

          1. All cement to be used or furnished shall be Type II low alkali portland cement
             conforming to ASTM C 150 or Type IP (MS) portland-pozzolan cement
             conforming to ASTM C 595, unless otherwise specified. Either cement shall
             conform to the low alkali requirements of Table IA of ASTM C150. Type IP (MS)
             cement shall contain no more than 20 percent pozzolan, which shall be
             interground with the clinker.

          2. Aggregates shall be nonreactive when tested in accordance with ASTM C 289
             and evaluated in accordance with Appendix A-1 of ASTM C 33. Aggregates
             found to be potentially reactive may be used only upon written acceptance of the
             ENGINEER.

      B. All pipe manufactured under the provisions of this Specification shall contain a
         minimum of 560 LB of cement per cubic yard of concrete unless mix designs with a
         lower cement content meet the requirements of this Specification and approved by
         the ENGINEER prior to use.

      C. Cement Mortar: Cement mortar shall consist of a mixture of portland cement, sand,
         and water. Cement and sand shall first be combined in the proper proportions, and
         then thoroughly mixed with the required amount of water. Cement mortar shall be
         proportioned by loose volume in the proportion of 1 part cement to 2 parts sand. The
         quantity of water to be used in the preparation of mortar shall be only that required
         producing a mixture sufficiently workable for the purpose intended. Mortar shall be
         used as soon as possible after mixing and shall show no visible signs of setting prior

           cement mortar shall conform to Section 03300 and 03310 Cast-in-Place Concrete.

       D. Admixtures: No admixtures shall be used in mortar unless otherwise specified or
          accepted by the ENGINEER.

       E. Quick Setting Grout: Quick setting grout shall be high strength, non-staining grout
          accepted by the ENGINEER prior to use. It shall reach an initial set within
          90 minutes at 70 degrees F and shall reach minimum compressive strength of 2,500
          psi within 24 hours. Shrinkage shall be less than 0.1 percent when tested, using the
          test procedures of ASTM C 596. The grout shall be mixed, handled, and placed in
          accordance with the manufacturers written instructions.

       F. Gaskets for Concrete Pipe:        Unless otherwise specified, gaskets shall be
          manufactured from a synthetic elastomer conforming to SSPWC Section 208-3.

PART 3 - EXECUTION

3.1    INSTALLATION OF PIPE

       A. Pipe shall be laid to plan line and grade, with uniform bearing under the full length of
          the barrel of the pipe. Pipe shall be installed in accordance with SSPWC Section 306
          1.2. Suitable excavation shall be made to receive the socket or collar, which shall not
          bear upon the subgrade or bedding. Any pipe which does not conform +/- 0.05 feet
          to the design profile shown on the [Drawings] or shows any undue settlement after
          laying shall be taken up and relaid at the CONTRACTOR'S expense. Pipe shall be
          laid up-grade with the socket or collar ends of the pipe upgrade unless otherwise
          authorized by the ENGINEER. Concrete pipe with elliptical reinforcement shall be
          laid with the minor axis of the reinforcement cage in a vertical position.

3.2    FIELD JOINTING OF REINFORCED CONCRETE PIPE

       A. Field jointing shall be in conformance with the applicable provisions of SSPWC
          Section 306-1.2.4.
