Performance-Based Specifications and Control of Concrete Durability by Hans Beushausen,Luis Fernandez Luco Pdf
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.
Concrete Permeability and Durability Performance by Roberto J. Torrent,Rui D. Neves,Kei-ichi Imamoto Pdf
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.
Durability of Concrete by Mark Alexander,Arnon Bentur,Sidney Mindess Pdf
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’.

Fundamentals of Durable Reinforced Concrete by Mark G. Richardson Pdf
Durability failures in reinforced concrete structures are wasteful of resources and energy. The introduction to practice of European Standard EN 206-1 represents a significant shift in emphasis on the need to explicitly consider each potential durability threat when specifying and producing concrete. Fundamentals of Durable Reinforced Concrete presents the fundamental aspects of concrete durability including reinforcement corrosion, carbonation, chloride ingress, alkali-aggregate reaction, freeze/thaw damage, sulphate attack, chemical attack, cracking, abrasion and weathering. The background to the durability exposure classes in EN 206-1 is also explained. Future directions in performance-based specifications and mathematical modelling of degradation are presented. This book will be of particular interest to specifiers applying the principles of the new European Standard EN 206-1 for the first time, to postgraduate researchers in mathematical modelling of degradation mechanisms, to undergraduates of engineering, architecture and building technology, and students of advanced concrete technology who require a concise source of reference on concrete durability.
Written specifically for the young professional and addressing a growing need for a long service life with minimal maintenance, Concrete Durability takes a whole new look at the whole-life performance of structures. This text examines physical and chemical issues that can threaten the durability of concrete. It explores available options for achiev
Integrated Design and Environmental Issues in Concrete Technology by K. Sakai Pdf
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.

Corrosion of Steel in Concrete by Building Research Establishment. Centre for Concrete Construction,BRE Centre for Construction Construction,Great Britain. Department of the Environment, Transport and the Regions Pdf
This Digest is in three Parts. Part 1 examines the durability of steel in concrete. With Part 2 on investigation and assessment, and Part 3 on protection and remedial work, it sets out the basic principles for all those concerned with the design and maintenance of durable concrete structures: owners, tenants on repairing leases, architects, surveyors, engineers, material scientists and contractors. It also examines existing standards of construction and the lessons learned from the investigation of cases of corrosion in concrete. This part of the Digest, Part 1, explains the physical, chemical and electrochemical processes involved in the deterioration of reinforced concrete by corrosion; it summarises the mechanisms underlying protection, considers issues associated with the durability management of existing structures, and reviews best practice in designing and specifying reinforced and prestressed concrete for new structures to achieve durable whole-life performance. Part 2 considers how corrosion-induced deterioration in existing steel reinforced concrete structures is assessed and diagnosed. Part 3 describes the repair and protection of concrete structures subject to corrosion damage, or which are expected to need measures to minimise future damage or deterioration. Concrete durability is an area which is undergoing rapid technical development and change; this Digest describes future developments that are expected to have a major influence on the approaches and methodologies in this field. Digests 263, 264 and 265 are withdrawn.
Performance Criteria for Concrete Repair Materials by Randall W. Poston,Peter H. Emmons,Keith Evan Kesner,Alexander M. Vaysburd Pdf
The study reported herein is part of an overall investigation to develop performance criteria for cement-based repair materials. In Phase I of the study, preliminary criteria for dimensionally compatible repair materials were developed based on a review of the literature. This review concentrated on identifying pertinent material properties, appropriate test methods, and demonstrated field performance. Laboratory and field tests to evaluate the preliminary performance criteria were conducted in Phase II of the project Twelve candidate repair materials were selected for the experimental portion of the project Bach material was subjected to a series of standard and nonstandard laboratory tests to determine properties which were perceived to be of interest in a repair context and to provide some basic information about their behavior. These tests included: (a) unrestrained and restrained drying shrinkage, (b) modulus of elasticity, (c) tensile and compressive creep, (d) coefficient of thermal expansion, and (e) flexural, compressive, and direct tensile strengths. Concurrent field tests were also conducted to evaluate material durability. Results of the laboratory investigation are described herein. Results of laboratory and field performance tests will be correlated (Phase III) to provide a basis for development of performance criteria for cement-based materials that will provide durable concrete repairs.
