For more than 100 years, engineers at UW-Madison have been conducting an experiment pitting ordinary concrete against the test of time. The project, initiated by faculty member Morton O. Withey, began in 1910 as a 10-year test of the strength of concrete in the form of 6-by-12-inch cylinders. Dozens more cylinders were added in 1923, with a third batch in 1937.
