Committee on Concrete Dams, 1997 - 2006, 108 pages.
This Bulletin (136) addresses all aspects of the relationship between the specification of concrete for dams of all sizes, construction procedures, the properties of the hardened concrete and how quality control is used. The development of concrete for dams from the conceptual stage to finished product is described. It present a holistic approach, recognizing the interrelatedness of the design and construction process and the roles of both Designers and Constructors in the production of functional, durable and ecomonic concrete.
