Description

The main objective of this book is to provide a detailed overview on environmental technology applications of alkali-activated materials (including geopolymers). It discusses what novel possibilities alkali-activated materials provide in comparison to conventional materials in these applications (such as high-temperature ceramics, synthetic zeolites, or plastics). The specific environmental applications that are covered include: water and wastewater treatment; air pollution control; stabilization/solidification of hazardous wastes; and catalysts in chemical processes. In addition, a review of preparation methods, material properties, and the chemistry of alkali-activated materials is also provided from the viewpoint of environmental applications. It also discusses how well alkali-activated materials fit under the concept of green chemistry and how the life cycle analysis of these materials compares to conventional materials. At the moment, the research area covered by the book is being studied at an increasing pace. The main drivers for this interest include the low-energy and low-cost manufacturing process of alkali-activated materials; the possibility to utilize industrial byproducts as raw materials; and beneficial material properties comparable to conventional materials. It has already been verified that alkali-activated materials are very versatile in environmental applications. The current research in the field focuses on advanced manufacturing methods, material properties, and applications: for example, additive manufacturing; modification of surface chemistry; CO2 capture; and green catalysis. Alkali-activated Materials in Environmental Technology Applications will be a valuable reference resource for academic and industrial researchers, material scientists and chemists working in civil engineering, sustainable construction materials, and geopolymers, cement and concrete manufacturers and environmental engineers.
