inside diameter.
Where sulfate-resistant pipe is required and
concrete pipe is to be an option, specify Type II or
Type V cement. Specify Type II (moderate sulfate
resisting) cement when water-soluble sulfates (as
S04) in the soil are in the range of 0.1 to 0.2
percent and, for water, are in the range of 150 to
1,000 parts per million. Specify Type V (sulfate
resisting) cement when soils contain in excess of
0.2 percent water-soluble sulfate and water samples
contain in excess of 1,000 parts per million. In
areas where reactive aggregates are known to occur,
specify low alkali cement.
The following are requirements for LANTNAVFACENGCOM
projects: Pipe sizes under 300 mm (12 inch)
diameter shall be nonreinforced concrete pipe. Pipe
sizes 300 mm (12 inch) diameter through 600 mm (24
inch) diameter may be either reinforced or
nonreinforced concrete pipe. Pipe sizes larger than
600 mm (24 inch) diameter shall be reinforced
concrete pipe.
