Cement-lined steel or iron pipe is not a new approach to corrosion prevention. In 1836 the French Academy of Science reported the successful use of cement-lined pipe. They reported that, "Hydraulic cement, applied about 2.5 mm (0.1 inches) thick, is of all compositions, combining facility of application and cheapness, that which adheres the best to the casting, is the most indestructible, and prevents most effectually all oxidation (Corrosion) and consequent formation of tubercles. Of course, it is well documented that the great Roman aqueducts were constructed of hydraulic cement, forerunner of modern Portland cement.
