Concrete has clearly emerged as the most economical and durable material for the building of the vast majority of marine structures. Reinforced concrete too has overcome the technological problems making it a suitable material for the construction of advanced marine structures such as offshore drilling platforms, superspan bridges and undersea tunn

Marine Concrete Structures: Design, Durability and Performance comprehensively examines structures located in, under, or in close proximity to the sea. A major emphasis of the book is on the long-term performance of marine concrete structures that not only represent major infrastructure investment and provision, but are also required to operate with minimal maintenance. Chapters review the design, specification, construction, and operation of marine concrete structures, and examine their performance and durability in the marine environment. A number of case studies of significant marine concrete structures from around the world are included which help to reinforce the principles outlined in earlier chapters and provide useful background to these types of structures. The result is a thorough and up-to-date reference source that engineers, researchers, and postgraduate students in this field will find invaluable. - Covers, in detail, the design, specification, construction, and operation of marine concrete structures - Examines the properties and performance of concrete in the marine environment - Provides case studies on significant marine concrete structures and durability-based design from around the world

Concrete has clearly emerged as the most economical and durable material for the building of the vast majority of marine structures. Reinforced concrete too has overcome the technological problems making it a suitable material for the construction of advanced marine structures such as offshore drilling platforms, superspan bridges and undersea tunnels. As the world becomes increasingly ocean-oriented for energy and other resources it is predicted that construction activities during the 21st century will be dominated by concrete sea structures. The performance of concrete in the marine environment is presented here in a logical manner giving state-of-the-art reviews of the nature of the marine environment, the composition and properties of concrete, history of concrete performance in seawater, major causes of deterioration of concrete in the marine environment, selection of materials and mix proportioning for durable concrete, recommended concrete practice and repair of deteriorated marine structures. It is of value to any design or construction engineer responsible for marine structures.

Concrete is commonly regarded as a mundane, prosaic material whilst the sea is perceived as a fearsome environment, endowed with mystery. Mystery stems from lack of knowledge, and to that extent both concrete and sea have something in common-we fall a long way short of knowing enough about them. Fortunately we have learned enough from our investigations and experiences to be able to set the limits within which we should operate. It is important for the engineer to seek to quantify the effects of the environment on materials and structures so that these can be made safe and adequately durable for their intended economic life. This is especially true for marine structures. Thus the primary purpose of this book is to provide a useful synthesis of the behaviour of concrete and concrete structures in the marine environment. An outline of the content of the book is provided in the latter part of the first chapter and so will not be anticipated here. The chief aim throughout, however, is to work as far as possible within a context of the appropriate governing physical phenomena, giving due consideration to the mathematical relationships between them. Moreover, without intending to be a design manual, an introduction is given to the sources of information which designers are likely to use, as well as to structural achievements. It is hoped that there should emerge an implicit integration between structure and constituent materials and the surrounding environment.

One marker of the majesty of ancient Rome is its surviving architectural legacy, the stunning remains of which are scattered throughout the circum-Mediterranean landscape. Surprisingly, one truly remarkable aspect of this heritage remains relatively unknown. There exists beneath the waters of the Mediterranean the physical remnants of a vast maritime infrastructure that sustained and connected the western world’s first global empire and economy. The key to this incredible accomplishment and to the survival of structures in the hostile environment of the sea for two thousand years was maritime concrete, a building material invented and then employed by Roman builders on a grand scale to construct harbor installations anywhere they were needed, rather than only in locations with advantageous geography or topography. This book explains how the Romans built so successfully in the sea with their new invention. The story is a stimulating mix of archaeological, geological, historical and chemical research, with relevance to both ancient and modern technology. It also breaks new ground in bridging the gap between science and the humanities by integrating analytical materials science, history, and archaeology, along with underwater exploration. The book will be of interest to anyone interested in Roman architecture and engineering, and it will hold special interest for geologists and mineralogists studying the material characteristics of pyroclastic volcanic rocks and their alteration in seawater brines. The demonstrable durability and longevity of Roman maritime concrete structures may be of special interest to engineers working on cementing materials appropriate for the long-term storage of hazardous substances such as radioactive waste. A pioneering methodology was used to bore into maritime structures both on land and in the sea to collect concrete cores for testing in the research laboratories of the CTG Italcementi Group, a leading cement producer in Italy, the University of Berkeley, and elsewhere. The resulting mechanical, chemical and physical analysis of 36 concrete samples taken from 11 sites in Italy and the eastern Mediterranean have helped fill many gaps in our knowledge of how the Romans built in the sea. To gain even more knowledge of the ancient maritime technology, the directors of the Roman Maritime Concrete Study (ROMACONS) engaged in an ambitious and unique experimental archaeological project – the construction underwater of a reproduction of a Roman concrete pier or pila. The same raw materials and tools available to the ancient builders were employed to produce a reproduction concrete structure that appears to be remarkably similar to the ancient one studied during ROMACON’s fieldwork between 2002-2009. This volume reveals a remarkable and unique archaeological project that highlights the synergy that now exists between the humanities and science in our continuing efforts to understand the past. It will quickly become a standard research tool for all interested in Roman building both in the sea and on land, and in the history and chemistry of marine concrete. The authors also hope that the data and observations it presents will stimulate further research by scholars and students into related topics, since we have so much more to learn in the years ahead.

Describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments.

The two themes of integration of structural and durability design, and integration of concrete technologies in relation to global environmental issues are drawn together in this book. It presents the views of distinguished international researchers and engineers on these key topics as the 21st century approaches. Derived from a workshop on rational design of concrete structures held in Hakodate, Japan, in August 1995, the book provides a focus for debate about the ways in which concrete technologies around the world must respond to the necessity of ensuring that concrete construction achieves higher levels of durability, and about the growing imperative to meet higher environmental standards in concrete production and use.

By designing in corrosion prevention and through preventive maintenance, the overall service cost of a concrete structure can be substantially reduced. This book takes a probabilistic approach to the engineering design issues for controlling durability and service life of concrete structures in severe environments. Many durability problems are caused by poor quality control as well as special problems during concrete construction. The issue of construction quality and variability need to be grasped before durability can be successfully controlled. This book helps by giving: reviews of field performance, deteriorating processes and current codes and practice methods for calculation of corrosion probability; performance-based concrete quality control; corrosion prevention and preventive maintenance calculation of life cycle costs and life cycle assessment recommended job specifications. Internationally relevant with a practical focus, this is the essential guide for consulting and construction engineers involved in the design and execution of new concrete structures.
