An excellent quality of cement is made in scores of factories in the West and sold at relatively low prices, while the other ingredients of sand, gravel, rock-dust, and broken rock usually are found in close proximity to where the pipe is Fig. 1.—Form used in incasing riveted steel pipe with concrete. Concrete pipe is made both reinforced and plain, the former having more or less steel embedded in the concrete shell in order to increase its tensile strength. A few years ago plain concrete pipe was placed in the same class as vitrified clay pipe as regards tensile strength and limited to less than 15 feet head. This precaution was then necessary owing to the inferior quality of the pipe made, and failures were common even under less than 10-foot heads. In recent years a marked improvement has been produced by substituting a proper concrete mixture for the cement and sand formerly used and.
