ICOLD Bulletin: The Physical Properties of Hardened Conventional Concrete in Dams
As submitted for ICOLD review, March 2008 iii
ACKNOWLEDGEMENTS
This Bulletin was drafted under the auspices of the ICOLD Committee on Concrete
Dams. The Bulletin was initiated under the Committee Chairmanship of J.R. Graham
(USA), and completed under the Chairmanship of R.G. Charlwood (USA/Canada).
The lead author of the Bulletin initially was P. Bertacchi (Italy) and since 1996 has been
M. Berra (Italy) who has developed and completed the document.
H. Kreuzer (Switzerland) provided a precious assistance in reviewing and editing.
The initial drafting team included P. Bertacchi, M. Berra, G. Ferrara & P. Morabito
(Italy), V. Ukrainczyk (Croatia), R. Charlwood (Canada), M. Machado (Portugal), J.
Alemo (Sweden) and T. Liu (USA).
The final Bulletin was drafted as follows:
Section 1 - Introduction, was prepared by P. Bertacchi and M. Berra (Italy).
Section 2 – Strength Properties, was initially drafted by V. Ukrainczuk (Croatia) and
subsequently redrafted by H. Kreuzer (Switzerland) with inputs regarding sonic
measurements from M. Berra (Italy).
Section 3 – Elastic Properties, was initially drafted by R. Charlwood (USA/Canada) and
subsequently completed by M. Berra (Italy) with inputs from H. Kreuzer and M. Conrad
(Switzerland) and J. Buil Sanz (Spain).
Section 4 – Creep Properties, was drafted by T.C. Liu (USA) and completed with
contributions from M. Berra (Italy) and H. Kreuzer ((Switzerland).
Section 5 – Shrinkage, was drafted by M. Berra (Italy).
Section 6 – Thermal Properties, was drafted by P. Morabito (Italy) and completed with
contributions of M. Berra (Italy) and H. Kreuzer ((Switzerland).
Section 7 – Water Permeability, was initially drafted by J. Alemo (Sweden) and
subsequently redrafted by T. Ekstrom (Sweden) with contributions from H. Kreuzer
(Switzerland) and M. Berra (Italy).
Section 8 – Frost Resistance, was drafted by M. Berra (Italy) with inputs from H.
Kreuzer (Switzerland).
Appendix A – Fracture Energy: application for dams, was drafted by G. Ferrara and
G.A. Plizzari (Italy) with inputs from H. Kreuzer (Switzerland) on size effects and biaxial
testing.
Appendix B – Physical Properties of Construction Joints in Concrete Dams, was drafted
by F. R. Andriolo and W.A. Pacelli (Brazil), G.S. Sarkaria (USA) with inputs from V.
Zipparrro (USA), M. Berra (Italy), M. Guerinet (France) and J. Buil Sanz (Spain).
Appendix C – Physical Properties of Concrete Subjected to Expansion Phenomena
such as AAR in Dams, was drafted by R. Charlwood (USA/Canada) with inputs from D.
Curtis (Canada) and subsequently completed and edited by M. Berra (Italy).
