Advanced Fiber-Reinforced Alkali-Activated Composites: Design, Mechanical Properties, and Durability covers various fiber types and their usage as a sustainable material as well as their influence on mechanical properties and behavior, including compressive strength, tensile strength, flexural strength, and impact and bond resistance. Their durability in different environments (seawater, magnesium sulphate, sulphuric acid, elevated temperature, corrosive) is also discussed. The book also outlines a variety of mix design and curing regimes for alkali-activated composites. The additive manufacturing of these composites is also covered. Different types of fiber-reinforced alkali-activated composites discussed include steel fiber-reinforced, carbon fiber-reinforced, natural fiber-reinforced, synthetic fiber-reinforced, and others. - Discusses different fiber types and their effects on alkali-activated composite materials - Includes coverage of compressive strength, tensile strength, flexural strength, impact and bond resistance, and more - Investigates the durability of these materials, studying how they perform in seawater, elevated temperature environments, and under sulphuric acid attacks - Covers the shrinkage resistance, permeability and corrosion performance of these materials

During roadway repairs, state highway officials try to minimize lane closure times. This reduces inconvenience to travelers, reduces traffic control needs, and helps minimize work zone accidents. For rapid repairs, materials that provide high early strength are needed. Pyrament blended cement (PBC) is marketed to produce concretes having a high early strength and long-term durability in varying climatic conditions. Concretes containing PBC were placed in full-depth patches in August 1989 and March 1990 under different temperature conditions. Type III cement concretes were used as controls in patches placed during August only, since specifications did not permit their use when the ambient temperature was below 13°C (55°F). Tests of the concretes and the field performance of the patches indicated that PBC concrete has high early and 28-day strengths, even in cold weather, and that the temperature and strength development is faster than in the control concretes. PBC concretes have the low permeability needed for durability and provide satisfactory resistance to freezing and thawing without the addition of an admixture during mixing.

What can be done about the major concerns of our Global Economy on energy, global warming, sustainable development, user-friendly processes, and green chemistry? Here is an important contribution to the mastering of these phenomena today. Written by Joseph Davidovits, the inventor and founder of geopolymer science, it is an introduction to the subject for the newcomers, students, engineers and professionals. You will find science, chemistry, formulas and very practical information (including patents' excerpts) covering: - The mineral polymer concept: silicones and geopolymers, - Macromolecular structure of natural silicates and aluminosilicates, - Scientific Tools, X-rays, FTIR, NMR, - The synthesis of mineral geopolymers, Poly(siloxonate) and polysilicate, soluble silicate, Chemistry of (Na, K)oligo-sialates: hydrous alumino-silicate gels and zeolites, Kaolinite / Hydrosodalite-based geopolymer, Metakaolin MK-750-based geopolymer, Calcium-based geopolymer, Rock-based geopolymer, Silica-based geopolymer, Fly ash-based geopolymer, Phosphate-based geopolymer, Organic-mineral geopolymer, - Properties: physical, chemical and long-term durability, - Applications: Quality controls, Development of user-friendly systems, Castable geopolymer, industrial and decorative applications, Geopolymer / fiber composites, Foamed geopolymer, Geopolymers in ceramic processing, Manufacture of geopolymer cement, Geopolymer concrete, Geopolymers in toxic and radioactive waste management. It is a textbook, a reference book instead of being a collection of scientific papers. Each chapter is followed by a bibliography of the relevant published literature including 75 patents, 120 tables, 360 figures, 550references, 700 authors cited, representing the most up to date contributions of the scientific community. The industrial applications of geopolymers with engineering procedures and design of processes are also covered in this book.

This state-of-the-art report summarizes the results of an extensive search and review of available literature on the mechanical properties of concrete, with particular reference to high performance concrete for highway applications. Included in the review and discussion are the behavior of plastic concrete as well as the strength and deformation characteristics of hardened concrete. Both short-term and long-term effects are considered. Based on the review of the available information, research needs are identified. It is concluded that much research is needed to develop data on the strength and durability properties of concrete which develops high strength, particularly very early strength.
