Science and Technology of Concrete Admixtures

Science and Technology of Concrete Admixtures presents admixtures from both a theoretical and practical point-of-view. The authors emphasize key concepts that can be used to better understand the working mechanisms of these products by presenting a concise overview on the fundamental behavior of Portland cement and hydraulic binders as well as their chemical admixtures, also discussing recent effects in concrete in terms of rheology, mechanics, durability, and sustainability, but never forgetting the fundamental role played by the water/binder ratio and proper curing in concrete technology. Part One presents basic knowledge on Portland cement and concrete, while Part Two deals with the chemical and physical background needed to better understand what admixtures are chemically, and through which mechanism they modify the properties of the fresh and hardened concrete. Subsequent sections present discussions on admixtures technology and two particular types of concrete, self-consolidating and ultra-high strength concretes, with final remarks on their future. Combines the knowledge of two leading authors to present both the scientific and technology of admixturesExplains what admixtures are from a chemical point-of-view and illustrates by which mechanisms they modify the properties of fresh and hardened concretePresents a fundamental, practical, and innovative reference book on the topic Contains three detailed appendices that can be used to learn how to use admixtures more efficiently INDICE: Preface Table of content Introduction Terminology and definitions Glossary Historical background of the development of concrete admixtures Part 1: Theoretical background on Portland cement and concrete Chapter 1 Water-cement and water-binder ratios Chapter 2 Phenomenology of cement hydration Chapter 3 Portland cement Chapter 4 Supplementary cementitious materials and fillers Chapter 5 Water Chapter 6 Entrained air Chapter 7 Concrete rheology Chapter 8 Mechanisms of cement hydration Part 2: Chemistry and working mechanisms Chapter 9 Chemistry of chemical admixtures Chapter 10 Adsorption of chemical admixtures Chapter 11 Working mechanisms of water reducers and superplasticizers Chapter 12 Impact of chemical admixtures on cement hydration Chapter 13 Working mechanisms of Shrinkage Reducing Admixtures Chapter 14 Working Mechanisms of Corrosion of Reinforcing Steel Part 3: The technology of admixtures Chapter 15 Formulation of chemical admixtures Chapter 16 Superplasticizers in practice Chapter 17 Air entraining agents Chapter 18 Retarders Chapter 19 Accelerators Chapter 20 Viscosity modifiers Chapter 21 Antifreezing admixtures Chapter 22 Expansive admixtures Chapter 23 Shrinkage modifiers Chapter 24 Corrosion inhibition Chapter 25 Curing membranes and evaporation retarders Parts 4 and 5: Special concretes and the Future of Admixtures Chapter 26 Self-consolidating concrete Chapter 27 Ultra-high strength concrete Chapter 28 Conclusion and outlook Appendices
