AWWA C104/A21.4-95

This standard covers shop-applied, cement-mortar linings specified in the ANSI/AWWA C100/A21 series of standards for ductile-iron pipe and ductile-iron and gray-iron fittings for water and is intended to be used as a supplement to those standards. The main purpose of this standard is to provide the minimum requirements for shop-applied, cement-mortar linings for ductile-iron pipe and ductile-iron and gray-iron fittings for water, including requirements for cement, sand, water, and mortar; surface of pipe and fittings for lining; method and thickness of lining; and curing. The major revisions to this edition of ANSI/AWWA C104 include the following: The format has been changed to current AWWA standard style; Section 4.1 on cement has been expanded to include types of cement other than portland; The size range covered by the standard has been expanded to include 3-in. through 64-in (76-mm through 1,600-mm) sizes; Section 4.11 on seal coat has been revised to allow the manufacturer the option of providing the cement-mortar lining with or without a seal coat unless otherwise specified. Also, the option of using seal-coat materials other than an asphaltic material has been deleted.
