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.

This reference book presents the theory and methodology to conduct a finite element assessment of concrete structures subjected to chemically induced volumetric expansion in general and alkali aggregate reaction in particular. It is limited to models developed by the author, and focuses on how to best address a simple question: if a structure suffers from AAR, how is its structural integrity jeopardized, and when would the reaction end. Subjects treated are: • Brief overview of AAR: nature of the chemical reactions, AAR in both dams and nuclear power plants, and how does it impact the mechanical properties of concrete. • Constitutive model for both the AAR expansion, and concrete nonlinearities (both smeared and discrete crack models). • Validation of the model along with a parametric study to assess what are the critical parameters in a study. • Selection of material properties for an AAR finite element simulation, followed by applications in dams and massive reinforced concrete structures. • Micro Model for improved understanding of the essence of the reaction, along with a newly proposed mathematical model for the kinetics of the reaction. • Review of relevant procedures to estimate the residual expansion of a structure suffering from AAR, along with a proposed approach to determine when the reaction will end. The book is extensively illustrated with numerous figures and provides guidance to engineers confronted with swelling in concrete infrastructures.

This self-contained book focuses on the safety assessment of existing structures subjected to multi-hazard scenarios through advanced numerical methods. Whereas the focus is on concrete dams and nuclear containment structures, the presented methodologies can also be applied to other large-scale ones. The authors explains how aging and shaking ultimately lead to cracking, and how these complexities are compounded by their random nature. Nonlinear (static and transient) finite element analysis is hence integrated with both earthquake engineering and probabilistic methods to ultimately derive capacity or fragility curves through a rigorous safety assessment. Expanding its focus beyond design aspects or the state of the practice (i.e., codes), this book is composed of seven sections: Fundamentals: theoretical coverage of solid mechnics, plasticity, fracture mechanics, creep, seismology, dynamic analysis, probability and statistics Damage: that can affect concrete structures, such as cracking of concrete, AAR, chloride ingress, and rebar corrosion, Finite Element: formulation for both linear and nonlinear analysis including stress, heat and fracture mechanics, Engineering Models: for soil/fluid-structure interaction, uncertainty quantification, probablilistic and random finite element analysis, machine learning, performance based earthquake engineering, ground motion intensity measures, seismic hazard analysis, capacity/fragility functions and damage indeces, Applications to dams through potential failure mode analyses, risk-informed decision making, deterministic and probabilistic examples, Applications to nuclear structures through modeling issues, aging management programs, critical review of some analyses, Other applications and case studies: massive RC structures and bridges, detailed assessment of a nuclear containment structure evaluation for license renewal. This book should inspire students, professionals and most importantly regulators to rigorously apply the most up to date scientific methods in the safety assessment of large concrete structures.

Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction--the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment--coagulation, filtration, membrane processes, chemical oxidation, and others--are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in each area considered. 1972 640 pp.
