This title is based on the workshop on Transport Properties & Concrete Quality, held at the campus of Arizona State University on October 10-12, 2005. During this meeting, scientific aspects of the relevant relationships between materials, mechanisms, processes, and service life were discussed. * Provides a useful resource for understanding the most valuable aspects of cement-based materials, with topics ranging from the current state of practice, to theory, simulation, and testing and specifications. * Logically organized and carefully selected articles give insight into the need to better integrate aspects of materials science, mechanics, modeling, and testing in developing tools of understanding the durability in cement-based materials.
Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities.This volume is a compilation of the Opening Addresses and Leader Papers for the five Conferences and fove Seminars held during the Congress, Creating with Concrete, 6-10 September 1999, organised by the Concrete Technology Unit, University of Dundee.
Whilst most structures made using concrete and cement-based composites have not shown signs of premature degradation, there have been notable exceptions. In addition, there is increasing pressure for new structures to remain in serviceable condition for long periods with only minimal maintenance before being recycled. All these factors have highlighted the issues of what affects the durability of these materials in different circumstances and how material properties can be measured and improved. Durability of concrete and cement composites summarises key research on these important topics.After an introductory chapter, the book reviews the pore structure and chemistry of cement-based materials, providing the foundation for understanding the particular aspects of degradation which are discussed in the following chapters. These include dimensional stability and cracking processes, chemical and microbiological degradation of concrete, corrosion of reinforcing and prestressing steels, deterioration associated with certain aggregates, effects of frost and problems involving fibre-reinforced and polymer-cement composites.With its distinguished international team of contributors, Durability of concrete and cement composites is a standard reference for all those concerned with improving the service life of structures using these materials. - Analyses a range of materials such as reinforced steel in concrete, pre-stressed concrete and cement composites - Discusses key degradation phenomena such as cracking processes and the impact of cold weather conditions - A standard reference for those concerned with improving the service life of structures using concrete and cement based composites
This book attempts to bring together some of the basic intricacies in the production of the complete range of self-consolidating cementitious composites, with a proper understanding of the contributions of different materials and their combinations, including performance and limitations. Presents a comprehensive perspective of the state of the art in self-compacting concretes while explaining the basic background and principles, includes possible alternatives of making SCC with different powder extenders and pozzolanic materials Explores concepts through theoretical and graphical representations
The use of novel materials and new structural concepts nowadays is not restricted to highly technical areas like aerospace, aeronautical applications or the automotive industry, but affects all engineering fields including those such as civil engineering and architecture. Addressing issues involving advanced types of structures, particularly those based on new concepts or new materials and their system design, contributions highlight the latest developments in design, optimisation, manufacturing and experimentation. Also included are contributions on new software, numerical methods and different optimisation techniques. Optimisation problems of interest involve those related to size, shape and topology of structures and materials. Most high performance structures require the development of a generation of new materials, which can more easily resist a range of external stimuli or react in a non-conventional manner. Particular emphasis is placed on intelligent structures and materials as well as the application of computational methods for their modelling, control and management. Optimisation techniques have much to offer to those involved in the design of new industrial products. The formulation of optimum design has evolved from the time it was purely an academic topic, able now to satisfy the requirements of real life prototypes. The development of new algorithms and the appearance of powerful commercial computer codes, with easy to use graphical interfaces, have created a fertile field for the incorporation of optimisation in the design process in all engineering disciplines. This proceedings volume is the first from a new edition of the High Performance Design of Structures and Materials and the Optimum Design of Structures conferences, which follows the success of a number of meetings that originated in 1989. Topics covered include: Composite materials & structures; Material characterisation; Experiments and numerical analysis; Steel structures; High performance concretes; Natural fibre composites; Transformable structures; Lightweight structures; Timber structures; Environmentally friendly and sustainable structures; Emerging structural applications; Optimisation in civil engineering; Evolutionary methods in optimisation; Shape and topology optimisation; Aerospace structures; Structural optimisation; Biomechanics application; Material optimisation; Life cost optimisation; Intelligence structures and smart materials.
The response of concrete under tensile loading is crucial for most applications because concrete is much weaker in tension than in compression. Understanding the response mechanisms of concrete under tensile conditions is therefore key to understanding and using concrete in structural applications. Understanding the Tensile Properties of Concrete Second Edition summarises key recent research in this important subject area. After an introduction to concrete, the book is divided into two parts: part one on static response and part two on dynamic response. Part one starts with a summary chapter on the most important parameters that affect the tensile response of concrete. Chapters show how multi scale modelling is used to relate concrete composition to tensile properties. Part two focuses on dynamic response and starts with an introduction to the different regimes of dynamic loading, ranging from the low frequency loading by wind or earthquakes up to the extreme dynamic conditions due to explosions and ballistic impacts. Following chapters review dynamic testing techniques and devices that deal with the various regimes of dynamic loading. Later chapters highlight the dynamic behaviour of concrete from different viewpoints, and the book ends with a chapter on practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications. Drawing on the work of some of the leading experts in the field, the book is fully updated and will be a valuable reference for civil and structural engineers as well as those researching this important material. - Presents recent research in the areas of understanding the response mechanisms of concrete under tensile conditions - Provides a summary of the most important parameters that affect the tensile response of concrete and shows how multi scale modeling is used to relate concrete composition to tensile properties - Highlights the dynamic behavior of concrete from different viewpoints and provides practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications - Presents recent advancements in tensile strength determination under static and dynamic loading conditions for concrete structures - Covers HSFRC and FRHSC - Presents new work on non-local models and damage modeling, the dynamic increase factor for tensile strength, fracture energy and anchors, and slop stabilization
