Dam Design and Construction, Reservoirs and Balancing Lakes

 · Among large dams there is extreme diversity of height, storage, river flow, range of cost, purpose, foundation, and dam types. The main differences are summarized below: 2.1 Number of dams over 15 m according to height and dam material. Over 50 percent of higher dams are in concrete but 90 percent of all dams under 30 m high are fill dams.

EARLY HISTORY OF MASS CONCRETE

cracks were due to internal heating and the Riverside Cement Company was absolved of blame. In 1931, research was begun at U.C. Berkeley on cement for the Hoover Dam. This dam was to be almost double the height of any dam up to that time and it was to be so thick that unless artificially cooled, the interior would stay warm for hundred of years.
