Abstract:
Five past presidents of the American Concrete Institute and an editor of engineering periodicals review and evaluate a quarter-century of progress in concrete theory, design and practice. Problems of 25 years ago are recalled, and the extent to which they have been solved discussed. Landmarks of progress are enumerated; today's problems (both new and old) are acknowledged. Difficulties encountered in formulating standards are reviewed; progressive changes in cement specifications are listed. Suggestions are made for continuing research programs and improved research techniques. Inspection practices are criticized and corrections suggested; the importance of consistency control and air entrainment effect are stressed. The history of alkali reaction studies is outlined. Important steps in structural design and theory are pointed out in some detail; there is a similar emphasis on progress of durability studies, and special mention is made of developments in highway construction.
