| Résumé : |
This book is in response to a need for presentation of the available knowledge in a logical and comprehensive manner.
Chapter 1 of the book contains a description of the various types of marine structures, and some examples of sophisticated concrete structures that have either been recently built or under construction. In Chapter 2, a description of the marine environment is given including the chemistry of seawater, marine organisms, typical temperature and hydrostatic pressure conditions in the oceans, tidal action, storm waves, and impact from floating ice. Chapter 3 contains a review of the composition, microstructure, and engineering properties of normal portland cement concrete. In Chapter 4, several case histories of concrete deterioration as a result of long exposure to seawater are described. This chapter is followed by a comprehensive discussion, in Chapter 5, of the physical and chemical causes of deterioration of reinforced concrete in seawater. Discussed in particular are the phenomena of corrosion of reinforcing steel, expansion and cracking of concrete by freezing and thawing cycles, sulfate and alkali-silica attacks, crystallization pressure of salts, and microorganism attack on concrete.
Chapter 6 contains comprehensive information on the selection of materials and mix proportions for concrete mixtures that may be required to show long-term durability in seawater. A new method of proportioning highly durable concrete, containing superplasticizing and pozzolanic admixtures, is described. Recommended construction practice (i.e., mixing, transport, placement and curing) is briefly discussed in Chapter 7. Since many old marine structures are in various states of deterioration, a rather detailed description of repair and rehabilitation of deteriorated concrete is presented in Chapter 8. In particular, procedures for evaluation of the condition of a structure before repairing, and guidelines for the selection of repair materials and methods are given.
The author hopes that this simple book will serve the need of practicing engineers involved in the design and construction of concrete sea structures. It is also hoped that the book is useful to civil engineering educators, who have the responsibility of training tomorrow's designers and builders of structures. |
