Indeed, thepressure for change and improvement of performance is relentless and necessary.The Concrete Technology Unit (CTU) of the University of Dundee organised this Congress toaddress these issues, continuing its established series of events, namely, Creating with Concretein 1999, Concrete in the Service of Mankind in 1996, Economic and Durable ConcreteConstruction Through Excellence in 1993 and Protection of Concrete in 1990.The event was organised in collaboration with three of the world's most recognised institutions:the Institution of Civil Engineers, the American Concrete Institute and the Japan Society of CivilEngineers. Under the theme of Challenges of Concrete Construction, the Congress consisted ofthree Seminars: (i) Composite Materials in Concrete Construction, (ii) Concrete Floors andSlabs, (iii) Repair, Rejuvenation and Enhancement of Concrete, and three Conferences: (i)Innovations and Developments in Concrete Materials and Construction, (ii) Sustainable ConcreteConstruction, (iii) Concrete for Extreme Conditions. In all, a total of 350 papers were presentedfrom 58 countries.The Opening Addresses were given by Mr Jack McConnell MSP, First Minister of the ScottishExecutive, Sir Alan Langlands, Principal and Vice-Chancellor of the University of Dundee, MrJohn Letford, Lord Provost, City of Dundee, Professor Adrian Long, Senior Vice-President of theInstitution of Civil Engineers, Dr Taketo Uomoto, Director of the Japan Society of CivilEngineers and Dr Terence Holland, President of the American Concrete Institute. The Congresshad six Opening and six Closing Papers dealing with the main themes of the Seminars andConferences. Opening Papers were presented by Professor Gerard Van Erp, University ofSouthern Queensland, Australia Dr Peter Seidler, Astradur Industrieboden, Germany andProfessor Kyosti Tuttii, Skanska Teknik AB, Sweden, Professor Surendra Shah, NorthwesternUniversity, USA, Dr Philip Nixon, Building Research Establishment, UK and Mr Hans de Vries,Ministry of Transport, the Netherlands. Closing Papers were presented by Dr Gier Horrigmoe,NORUT Technology Ltd, Norway, Professor Andrew Beeby, University of Leeds, UK, ProfessorPeter Robery, FaberMaunsell, UK, Professor Heiki Kukko, VTT Building and Transport,Finland, Dr Mette Glavind, Danish Technological Institute, Denmark and Professor YoshihiroMasuda, Utsunomiya University, Japan. The Congress was closed by Professor Peter Hewlett,Chief Executive of the British Board of Agrement, UK.The support of 23 International Professional Institutions and 32 Sponsoring Organisations was amajor contribution to the success of the Congress. An extensive Trade Fair formed an integralpart of the event. The work of the Congress was an immense undertaking and all of thoseinvolved are gratefully acknowledged, in particular, the members of the Organising Committeefor managing the event from start to finish; members of the International Advisory and NationalTechnical Committees for advising on the selection and reviewing of papers; the Authors and theChairmen of Technical Sessions for their invaluable contributions to the proceedings.All of the proceedings have been prepared directly from the camera-ready manuscripts submittedby the authors and editing has been restricted to minor changes where it was consideredabsolutely necessary.Dundee Ravindra K DhirSeptember 2002 Chairman, Congress Organising Committeeiii  INTRODUCTION Concrete is a unique material in that it can resist extremes of heat, cold, water and load, yetprovide the engineer with an economic solution to the construction of complex buildings andinfrastructure. It has very few weak points and where these exist, eg acid chemical attack, itscomposition can be manipulated to provide satisfactory performance.As the limits of technology expand, so to do the conditions into which structures andelements must be placed. These include for example, deep water, the conditions to recoverhitherto inaccessible oil reserves and roads, which span deserts. Furthermore concrete has animportant role to play in containing the conditions associated with climate change,anticipated in the medium to long-term.Recent events illustrate that concrete must be able to cope with severe blasts and explosiveresponses. Indeed, the very future of tall structures may depend on the ability of concrete toresist occurrences, which even a few years ago would be unthinkable.The world is developing rapidly and populations are ever growing. As this occurs, the needfor structures for accommodation, business, commerce and education in areas where seismicactivity is commonplace, becomes ever more pressing. It is clearly the duty of the developedworld technologies to facilitate this.This century will also see increasing demands for energy, both fossil and nuclear andconcrete will play a central role in achieving this. Furthermore, the worlds nuclear generatingfacilities are ageing and the need for decommissioning and the nettle of the containment oftoxic and radioactive materials must be grasped. It can also be anticipated that this centurywill see concrete become extraterrestrial and thereby enable the further exploration andunderstanding of the universe.The Proceedings of this Conference  'Concrete for  Extreme  Conditions'  deals with all of thesesubject areas and the issues raised under six clearly defined themes: (i) Chemically andPhysically Aggressive environments, (ii) Marine and Underwater Concrete, (iii) Temperatureand Humidity Effects on concrete, (iv) Design for Accidental Damage, (v) Extreme LoadingConditions and (vi) Concrete for Specialist Situations. Each theme started with a KeynotePaper presented by the foremost components in their respective fields. There were a total of79 papers presented during the International Conference which are compiled into theseProceedings.Dundee Ravindra K DhirSeptember 2002 Michael J McCarthyMoray D Newlands
