Abstract:
In the process of moving the materials testing laboratory of Purdue University to a new building, a concrete test beam of the vintage of 1904 was unearthed. The beam had been tested to destruction in the laboratory and exposed at ground line for 24 summers and winters. The reinforcing steel embedded in the sound concrete was in perfect condition, even though there must have been fine cracks produced during loading. This may be taken as additional confirmation of the fact that fine cracks when drawn together again do not admit rust producing agents.
