Fernando Pacheco Torgal; J Labrincha; Cristina Leonelli; Angel Palomo Sánchez; P. Chindaprasirt ... 852 pages - Publisher: Woodhead Publishing; 1st edition (November, 2014) ... Language: English - ISBN-10: 1782422765 - ISBN-13: 978-1782422761 ...

This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet’s total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders + Considers performance in adverse environmental conditions. + Offers equal emphasis on the science behind the technology and its use in civil engineering.

    Ultrafine Cement in Pressure Grouting presents the technical and practical information required by engineers to plan and implement grouting programs that are cost effective and technically sound. As a key component of modern grouting programs, ultrafine cement is an ideal solution for geotechnical engineers and construction contractors who are grappling with the challenges of managing costs while developing sites that may be less than ideal. Increasingly, the virtues of ultrafine cement lead engineers and contractors to use it rather than the less-expensive portland cements. The authors concisely define ultrafine cement, describe its engineering properties, and explain its manufacture, packaging, and storage. Mixing and pumping procedures and quality control issues are covered, as well as recommendations for specifying ultrafine cement in contracts. An appendix offers 16 brief project descriptions. Ultrafine Cement in Pressure Grouting is a fundamental reference that will be consulted frequently by geotechnical engineers who specify grouting materials for construction projects.

    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 summarises key recent research in this important subject. 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, Understanding the tensile properties of concrete is a valuable reference for civil and structural engineers as well as those researching this important material. Summarises key 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 behaviour of concrete from different viewpoints and provides practical examples of how detailed knowledge on tensile properties is used by engineers in structural applications.

    H. F. W. Taylor was for many years Professor of Inorganic Chemistry at he University of Aberdeen, Scotland. Since 1948, his main research interest has been the chemistry of cement. His early work laid the foundations of our understanding of the structure at the nanometre level of C-S-H, the principal product formed when cement is mixed with water, and the one mainly reponsible for its hardening. Subsequent studies took him into many additional aspects of the chemistry and materials science of cement and concrete. His work has been recognized by Fellowships and by other honours and awards.

    Supplementary cementing materials (SCMs), such as fly ash, slag, silica fume, and natural pozzolans, make a significant difference to the properties of concrete but are rarely understood in any detail. SCMs can influence the mechanical properties of concrete and improve its durability in aggressive environments. Supplementary Cementing Materials in Concrete covers the chemical, physical, and mineralogical properties of SCMs; their chemical reactions; and the resulting changes in the microstructure of concrete.

    The author links the properties of the material at the microstructural level with its behavior in laboratory tests, and, in turn, to the performance of the material in concrete structures under field exposure. He explains how SCMs influence the mechanical properties of concrete and improve its durability and also covers how various SCMs influence hydration reactions and the evolution of the pore structure and pore-solution composition. However, SCMs are not a panacea for concrete and improper use may be injurious to certain properties. Achieving the maximum benefit from SCMs requires an understanding of the materials and how they impact concrete properties under various conditions. Drawing on the author’s 30 years of experience, this book helps engineers and practitioners to optimize the use of supplementary cementing materials to improve concrete performance.

    Special inorganic cements need to be used instead of standard Portland cement in certain specialist applications, such as oil well drilling or in a high temperature location. In other cases they might allow for lower production costs or a reduction in enviromental damage. No other book is dedicated to this subject, and it draws together information which is widely scattered in the technical literature. The various special cements are described, and their chemistry and mineralogy is outlined along with the appropriate manufacturing processes, their hydration and hydration properties, and their applications.

    Supplementary cementing materials and other mineral admixtures are being used in increasing amounts in both cement and concrete. Their main technical benefits are that they enhance the workability of fresh concrete and the durability of hardened concrete. Indeed, they affect almost every property of the concrete. Their economic and ecological benefits may be just as significant, and their use can be expected to increase as concrete remains the most common construction material.


    Cement and Concrete Mineral Admixtures concentrates mostly on natural pozzolans, fly ashes, ground granulated blast furnace slag, silica fume and limestone powder, namely the most commonly used mineral admixtures. Others such as metakaolin, rice husk ash, expanded clays and shales are also discussed. Their chemical, mineralogical, and physical properties are outlined. The influence of mineral admixtures on the hydration of cementitious systems, and the properties of fresh and hardened concrete in which they are used are emphasized. International standards are reviewed. The basics of concrete mix proportioning with mineral admixtures are outlined. The possibilities of using mineral admixtures as constituents of special concretes such as self-compacting, reactive powder, roller-compacted concretes and special non-portland, low-cost, low-energy and/or low-CO2 cements such as alinite, calcium sulfoaluminate, and belitic cements and alkali-activated binders are also covered. The book is a comprehensive reference for senior undergraduate and graduate students and researchers in the fields of cement and concrete, and for cement and concrete practitioners.

    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 monograph describes cement clinker formation. It covers multicomponent systems, clinker phase structures and their reactions with water, hydrate composition and structure, as well as their physical properties. The mineral additions to cement are described as are their influence on cement-paste properties. Special cements are also discussed. The microstructure of concrete is then presented, and special emphasis is given to the role of the interfacial transition zone, and the corrosion processes in the light of cement-phase composition, mineral additions and w/c ratio. The admixtures' role in modern concrete technology is described with an emphasis on superplasticizer chemistry and its cement-paste rheological modification mechanism. Cement with atypical properties, such as calcium aluminate, white, low energy and expansive cements are characterized. The last part of the book is devoted to special types of concrete such as self compacting and to reactive powders.

    Self-Compacting Concrete (SCC) is a relatively new building material. Nowadays, its use is progressively changing the method of concrete placement on building sites.

    However, the successful use of SCC requires a good understanding of the behavior of this material, which is vastly different from traditional concrete. For this purpose, a lot of research has been conducted on this area all over the world since 10 years.

    Intended for both practitioners and scientists, this book provides research results from the rheological behavior of fresh concrete to durability.
