Durability Design Of Concrete Structures In Severe Environments

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.

One of the most pressing problems facing the construction industry globally is the deterioration of major concrete infrastructure in marine and other chloride-containing environments. While recent advancements in concrete technology have made it easier to control the negative impact of deteriorating processes such as alkali-aggregate reaction, freezing and thawing and chemical attack, chloride-induced corrosion of embedded steel continues to pose the biggest threat to structure durability and performance. The second edition of Durability Design of Concrete Structures in Severe Environments focuses on enhancing the durability and service life of concrete structures. The text describes field experience and deteriorating processes of concrete structures in severe environments, and includes current data based on extensive field investigations. It presents a durability design based on calculation of corrosion probability, and outlines additional protective strategies and measures. The text also describes procedures for performance-based concrete quality control and quality assurance with documentation of achieved construction quality and compliance with specified durability. The text further covers calculation of life cycle costs and life cycle assessment, and includes some new recommended job specifications. What’s New in the Second Edition: This second edition delivers more results and experience from practical applications of the probability-based durability design and the performance-based concrete quality control. It includes recent commercial projects both for Oslo Harbor KF and Nye Tjuvholmen KS in Oslo, and contains some preliminary results from the more comprehensive research program "Underwater Infrastructure and Underwater City of the Future" at Nanyang Technological University in Singapore. The book serves as an essential guide both for the owners and the consulting and construction engineers involved in new and major concrete infrastructure design and construction.

Concrete structures can be designed for durability by applying the principles and procedures of reliability theory combined with traditional structural design. This book is the first systematic attempt to introduce into structural design a general theory of structural reliability and existing calculation models for common degradation processes. It covers both the theoretical background and practical design for service life and includes worked examples which highlight the application of the design procedure and methods.

This book provides an up-to-date survey of durability issues, with a particular focus on specification and design, and how to achieve durability in actual concrete construction. It is aimed at the practising engineer, but is also a valuable resource for graduate-level programs in universities. Along with background to current philosophies it gathers together in one useful reference a summary of current knowledge on concrete durability, includes information on modern concrete materials, and shows how these materials can be combined to produce durable concrete. The approach is consistent with the increasing focus on sustainability that is being addressed by the concrete industry, with the current emphasis on ‘design for durability’.

This design guide allies basic knowledge with current engineering experience of the durability of concrete structures. It presents appropriate solutions for different environmental conditions. The complex nature of environmental effects on structures requires improved materials, as well as measures at the architectural design phase, and proper inspection and maintenance procedures.

Following the very successful 1st conference in Sapporo, Japan in 1995, the 2nd conference presents a series of papers on concrete structures which are subjected to severe environmental forces. Recent experience of the performance of concrete structures has demonstrated the need for a better integration of structural and durability design; the development of new design concepts; and an improvement in the basis for the operation and maintenance of concrete structures, including repair and retro-fitting. This book addresses all these important issues.
