Description:
The program was undertaken to field test concrete sewer pipe that had been impregnated with sulfur or hydrofluoric acid. This program was a follow-on to a previous laboratory study sponsored by EPA entitled, Impregnation of Concrete Pipe, 11024EQE 06/71. In a subsequent grant extension to the program, strength improvements using the sulfur formulations were investigated with a view to reducing costs by elimination of the steel reinforcing in certain sizes of concrete pipe. In 1975, nearly 1400 feet (427 m) of impregnated sewer lines were installed in four Texas cities, including Dallas, Beaumont, Pecos, and Harlingen. These lines have been monitored since that time and the results of this monitoring, as well as a discussion of the strength improvement due to sulfur impregnation, are reported.
