    This specification covers nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients and for use in drainage. The concrete shall consist of cementitious materials, minerals, aggregates, and water. Cement shall conform to the requirements for Portland cement or shall be Portland blast-furnace slag cement, or slag modified Portland cement, or Portland-pozzolan cement conforming to the requirements except that the pozzolan constituent in the Type IP Portland-pozzolan cement shall be fly ash. The combination of cementitious materials used in the concrete shall be one of the following: Portland cement only, Portland blast furnace slag cement only, slag modified portland cement only, portland pozzolan cement only, a combination of Portland cement and fly ash, a combination of portland cement and ground-granulated blast-furnace slag or a combination of fly ash and ground granulated blast furnace slag. The specimens shall undergo external load test, absorption test and hydrostatic test. The material shall also conform to the required internal diameter and wall thickness.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers nonreinforced concrete pipe to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, as shown in Table 1 and for use in drainage.

    1.2 A complete SI companion to Specification C118 has been developedC118M; therefore, no SI equivalents are presented in this specification.

    Note 1—This specification is for manufacturing and purchase only and does not include requirements for bedding, backfill, installation, or field repairs. The owner is cautioned that he must correlate field conditions with the characteristics of the pipe specified and provide inspection during installation.

    A For hydrostatic test requirements, refer to 10.5.

    B Higher working pressures are not prohibited up to a maximum of 40 ft for 6 through 8-in. diameters, 35 ft for 10 through 12-in. diameters, and 30 ft. for 14-in. through 24-in. diameters. In these cases, the strength of the pipe shall be increased to give a minimum of at least four times the design working pressure when tested as specified in 10.5.
