This specification covers reinforced concrete low-head pressure pipe. Acceptability of the pipe in all diameters and classes shall be determined by the results of such material tests. The reinforced concrete shall consist of Portland cement, mineral aggregates, and water, in which steel has been embedded in such a manner that the steel and concrete act together. Portland cement shall conform to the requirements specified. Aggregates shall conform to the requirements specified, except that the requirements for grading are waived. Admixtures, except for air-entraining agents, shall not be added to the concrete unless permitted by the owner. Reinforcement shall consist of wire conforming to the requirements prescribed. Steel castings for fittings shall conform to grade 70-36. Steel plates for specials and fittings shall conform to requirements specified. All rubber gaskets shall be extruded or molded and cured in such a manner that any cross section will be dense, homogeneous, and free of porosity, blisters, pitting, and other imperfections. Joints shall utilize steel joint rings, steel bells and concrete spigots, or be formed entirely of concrete. The aggregates shall be graded, proportioned, and thoroughly mixed with the proportions of cementitious material and water that will produce a workable, uniform, homogeneous concrete mixture. Compression tests of cylinders and hydrostatic tests of pipes shall be performed to meet the requirements prescribed.
