Committee on Concrete Dams, 1991 - 2008, 262 pages
The purpose of this Bulletin (145) is to provide a comprehensive treatise on the physical properties of hardened conventional concrete for dams, refreshing the partial information contained in some out-of-date ICOLD Bulletins, giving ana account of new approaches and exaamining also some important properties not included in the previous Bulletins.
