This specification covers the standard requirements for porous nonreinforced concrete pipe for use in underdrains. The pipe shall be of two classes, identified as: “standard-strength porous nonreinforced concrete pipe” and “extra-strength porous nonreinforced concrete pipe.” The concrete shall consist of cementitious materials and water; wherein, the cement shall conform to the requirements for Portland cement or shall be Portland blast-furnace slag cement, slag-modified Portland cement, or Portland-pozzolan cement. The fly ash and ground granulated blast furnace slag shall conform to the requirements of Class F or C and Grade 100 or 120, respectively while the synthetic fibers shall be made of collated fibrillated virgin polypropylene fibers. Design requirements shall be in accordance with the internal designated diameter, wall thickness, laying length, socket depth, three-edge bearing strength, and infiltration or porosity. The pipe shall be subjected to steam curing, water curing, or combination of the two methods for a sufficient length of time to develop the specified strength requirement. Crushing tests shall be performed to determine the crushing strength of the pipes.The concrete shall consist of cementitious materials, mineral, aggregates, and water. The joints shall be of such design and the ends of the concrete pipe sections so formed that the pipe can be laid together to make a continuous line pipe. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials, and water as will produce a homogeneous concrete mixture of such quality that the pipe will conform to test and design requirements. Pipe shall be subjected to curing. Special shapes or fittings for use with concrete pipe conforming to this specification shall be made of porous or nonporous concrete in such manner as will provide strength at least equal to the class of the adjacent pipe to which they are joined; and shall conform to all other requirements specified for pipe. The test pipe shall freed from all visible moisture. When dry, each pipe shall be measured and inspected. The crushing strength of the porous material as well as its infiltration, shall conform to the requirements.
