Investigation of Polymer-Impregnated Concrete Pipe
The evaluation of structural and durability properties of polymer-impregnated concrete (PIC) pipe as compared with those of commercially manufactured concrete pipe is presented in three separate studies: (1) 4-inch-diameter concrete draintile, (2) 12- and 24-inch-diameter concrete sewer and culvert pipe, and (3) 36-inch-diamter concrete culvert pipe. Impregnation and polymerization of concrete pipe result in significant improvement in strength and durability. Polymer impregnation of concrete draintile increases the three-edge bearing strength from about 70 to 280 percent above that of the untreated pipe. The three-edge bearing strength of 12- and 24-inch unreinforced concrete sewer and culvert pipe was increased from about 110 to 150 percent by polymer impregnation. Unreinforced 36-inch-diameter PIC pipe exceeded the ASTM: C 76 requirements for ultimate three-edge bearing load by 50 to 90 percent. Polymer-impregnated 36-inch-diameter concrete pipe subjected to 5 percent sulfuric acid showed increases in resistance to sulfuric acid attack of from 2.8 to 7.8 times that of the untreated concrete pipe.
