Prediction of Concrete Durability


Book Description

Poor durability of concrete is a continuing concern to owners of structures and their professional advisors. Advances in methods of assessing and predicting durability are being made in many areas, and this book provides a state of art review of the current situation. Contributions from leading researchers and consultants make it a valuable guide for all those responsible for concrete buildings and structures.

Durability of Concrete


Book Description

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’.




Concrete Permeability and Durability Performance


Book Description

Durability and service life design of concrete constructions have considerable socio-economic and environmental consequences, in which the permeability of concrete to aggressive intruders plays a vital role. Concrete Permeability and Durability Performance provides deep insight into the permeability of concrete, moving from theory to practice, and presents over 20 real cases, such as Tokyo’s Museum of Western Art, Port of Miami Tunnel and Hong Kong-Zhuhai-Macao sea-link, including field tests in the Antarctic and Atacama Desert. It stresses the importance of site testing for a realistic durability assessment and details the "Torrent Method" for non-destructive measurement of air-permeability. It also delivers answers for some vexing questions: Should the coefficient of permeability be expressed in m2 or m/s? How to get a "mean" pore radius of concrete from gas-permeability tests? Why should permeability preferably be measured on site? How can service life of reinforced concrete structures be predicted by site testing of gas-permeability and cover thickness? Practitioners will find stimulating examples on how to predict the coming service life of new structures and the remaining life of existing structures, based on site testing of air-permeability and cover thickness. Researchers will value theoretical principles, testing methods, as well as how test results reflect the influence of concrete mix composition and processing.




Performance-Based Specifications and Control of Concrete Durability


Book Description

This work gives an overview of significant research from recent years concerning performance-based design and quality control for concrete durability and its implementation. In engineering practice, performance approaches are often still used in combination with prescriptive requirements. This is largely because, for most durability test methods, sufficient practical experience still has to be gained before engineers and owners are prepared to fully rely on them. This book, compiled by RILEM TC 230-PSC, is intended to assist efforts to successfully build the foundation for the full implementation of performance-based approaches through the exchange of relevant knowledge and experience between researchers and practitioners worldwide.










Durability Design of Concrete Structures


Book Description

Comprehensive coverage of durability of concrete at both material and structural levels, with design related issues Links two active fields in materials science and structural engineering: the durability processes of concrete materials and design methods of concrete structures Facilitates communication between the two communities, helping to implement life-cycle concepts into future design methods of concrete structures Presents state-of-the-art information on the deterioration mechanism and performance evolution of structural concrete under environmental actions and the design methods for durability of concrete structures Provides efficient support and practical tools for life-cycle oriented structural design which has been widely recognized as a new generation of design philosophy for engineering structures The author has long experience working with the topic and the materials presented have been part of the author's current teaching course of Durability and Assessment of Engineering Structures for graduate students at Tsinghua University The design methods and approaches for durability of concrete structures are developed from newly finished high level research projects and have been employed as recommended provisions in design code including Chinese Code and Eurocode 2




Concrete Durability


Book Description

Deterioration and distress of concrete structures in service is a result of a variety of physiochemical processes. These processes include attack by acids or alkali, cycles of wetting and drying, freezing and thawing, alkali - aggregate reaction, etc. However, the most serious deterioration process is caused by chloride diffusion mechanism which then leads to corrosion of reinforcing steel. Moreover, up to date, the accurate service-life prediction of reinforced concrete structures is getting more and more attention. Needless to say, the most advanced models on durability of concrete are found in the field of chloride-induced corrosion. However, most of them are built and developed based on the marine environment of Europe, America and a few countries from Asia, excluding Thailand and Vietnam. For this reason, the requirement of an accurate and suitable model for the local marine environment conditions of Thailand and Vietnam is very imperative because Thailand and Vietnam not only have the same environment conditions, but also have a long coast which mostly affect the durability of concrete structures.
