Abstract:
The maturity method is a technique to account for the
combined effects of time and temperature on the strength
development of concrete. The method provides a
relatively simple approach for making reliable estimates
of in-place strength during construction. The origin of
the method can be traced to work on steam curing of
concrete carried out in England in the late 1940s and
early 1950s. As a result of technology transfer efforts
by the Federal Highway Administration, there is renewed
interest in the method within the United States. The
purpose of this paper is to review of the basic concepts
underlying the method and to explain how the method is
applied. The review focuses on work carried out by
researchers at the National Institute of Standards and
Technology (formerly the National Bureau of Standards).
