Abstract:
No one could question the appropriateness of "Research on Concrete" as a topic for a Stanton Walker Lecture on the Materials Sciences. Research, according to Webster’s Dictionary, is "critical and exhaustive investigation or experimentation having as its aim the discovery of new facts and their correct interpretation; the revision of accepted conclusions, theories, or laws, in the light of newly discovered facts; or the practical applications of such new or revised conclusions." Dr. Bates noted, in the first of these lectures in 1963,1 that it had recently been said that "concrete is not a material, it is a process." However, in 1967, when the American Concrete Institute finally got around to publishing an official definition of concrete,2 hat definition read: "A composite material which consists essentially of a binding medium within which are embedded particles or fragments of aggregate; in portland cement concrete, the binder is a mixture of portland cement and water."
