16、rminology C822.4. Classification4.1 Pipe manufactured according to this specification shallbe for hydrostatic heads of 25, 50, 75, 100, and 125 ft measuredto the centerline of the pipe. Designs are provided in Table 1for the above hydrostatic heads combined with external load-ings of 5, 10, 15, and

17、20 ft (designated A, B, C, and D in Table1) of earth cover over the top of the pipe under specificinstallation conditions. The specific installation conditions arecovered in Appendix X1. Where the hydrostatic head, externalloadings, and installation conditions vary from those given inTable 1 and App

18、endix X1, detailed design calculations shall bemade. The design criteria for Table 1 are presented in Appen-dix X2.5. Basis of Acceptance5.1 Acceptability of the pipe in all diameters and classesshall be determined by the results of such material tests as arerequired in 6.2 through 6.9 by crushing t

19、ests on cured concretecylinders, by hydrostatic pressure tests on units of the pipe, byjoint leakage tests, and by inspection during or after manufac-ture to determine whether the pipe conforms to this specifica-tion as to design and freedom from defects.5.2 Age for AcceptancePipe shall be considere

20、d ready foracceptance when they conform to the requirements, as indi-cated by the specified tests.6. Materials6.1 Reinforced ConcreteThe reinforced concrete shallconsist of portland cement, mineral aggregates, and water, inwhich steel has been embedded in such a manner that the steeland concrete act

21、 together. Fly ash or pozzolan is not prohibitedwhen used as a partial cement replacement; see 9.1.6.2 Cementitious Materials:6.2.1 Cement:6.2.1.1 Portland CementPortland cement shall conform tothe requirements of Specification C150.6.2.1.2 Blended Hydraulic CementBlended cement shallconform to the
