A geopolymer is a solid aluminosilicate material usually formed by alkali hydroxide or alkali silicate activation of a solid precursor such as coal fly ash, calcined clay and/or metallurgical slag. Today the primary application of geopolymer technology is in the development of reduced-CO2 construction materials as an alternative to Portland-based cements. Geopolymers: structure, processing, properties and industrial applications reviews the latest research on and applications of these highly important materials.Part one discusses the synthesis and characterisation of geopolymers with chapters on topics such as fly ash chemistry and inorganic polymer cements, geopolymer precursor design, nano...
This is a State of the Art Report resulting from the work of RILEM Technical Committee 224-AAM in the period 2007-2013. The Report summarises research to date in the area of alkali-activated binders and concretes, with a particular focus on the following areas: binder design and characterisation, durability testing, commercialisation, standardisation, and providing a historical context for this rapidly-growing research field.
Sustainable Concrete Materials and Structures focuses on recent research progress and innovations in this important field of research. All aspects of the technical routes to sustainable concrete and structures are discussed in detail. These include recent findings on sustainable concrete production and structural design and construction. Low-carbon cement, sustainable concrete mix design, durability, and structural applications are discussed in detail. Emphasis is placed on how to bring some of the innovations in concrete technology closer to market. Information on techno-economic analysis, economy of scale, and the supply chain of sustainable concrete is also addressed. The book will be an ...
This book delves into the world of metakaolin (MK) and its impact on the properties of geopolymers. Beginning with an introduction to the abundance and versatility of kaolin, the author explores how calcination transforms it into the highly reactive material known as MK. The book investigates the incorporation of MK into different types of geopolymers and examines how factors such as precursor type and fineness, MK fineness, activator type and concentration, curing conditions, and testing age influence the resulting properties. Through a meticulous evaluation of prior studies, the text presents valuable insights into workability, setting time, density, compressive strength (with specific focus on slag, fly ash, and other precursors), flexural strength, splitting tensile strength, elastic modulus, porosity, water absorption, shrinkage, carbonation resistance, corrosion resistance, and other durability aspects. Drawing upon a wealth of knowledge, this work serves as a comprehensive reference for researchers and offers a roadmap for future investigations.
This book highlights the key role of green infrastructure (GI) in providing natural and ecosystem solutions, helping alleviate many of the environmental, social, and economic problems caused by rapid urbanization. The book gathers the emerging technologies and applications in various disciplines involving geotechnics, civil engineering, and structures, which are presented in numerous high-quality papers by worldwide researchers, practitioners, policymakers, and entrepreneurs at the 6th CIGOS event, 2021. Moreover, by sharing knowledge and experiences around emerging GI technologies and policy issues, the book aims at encouraging adoption of GI technologies as well as building capacity for implementing GI practices at all scales. This book is useful for researchers and professionals in designing, building, and managing sustainable buildings and infrastructure.
Geopolymer Concrete Structures with Steel and FRP Reinforcements: Analysis and Design focuses on structural behavior, including the aspects of compression, bending strength and combined action of GPC members, with the book's content based on published studies over the last two decades. Geopolymer concrete (GPC) structural members reinforced with FRP reinforcement have some advantages in resisting forces compared to conventional concrete or steel tubular members. Among the most important are the high strength and bending stiffness, fire and impact performance and favorable, construction ability and durability. To this end, there are no significant applications of these new structural elements...
The Ceramic Engineering and Science Proceeding has been published by The American Ceramic Society since 1980. This series contains a collection of papers dealing with issues in both traditional ceramics (i.e., glass, whitewares, refractories, and porcelain enamel) and advanced ceramics. Topics covered in the area of advanced ceramic include bioceramics, nanomaterials, composites, solid oxide fuel cells, mechanical properties and structural design, advanced ceramic coatings, ceramic armor, porous ceramics, and more.

Il testo, in seconda edizione riveduta e ampliata, riassume lo stato dell'arte delle conoscenze sui geopolimeri, leganti idraulici e materiali ceramici di tipo alluminosilicatico a bassissimo contenuto di calcio. L'attivazione alcalina porta alla parziale dissoluzione di materie prime, sia naturali che scarti industriali, che danno origine a paste lavorabili e consolidabili a freddo. La buona stabilità termica e lebuone proprietà meccaniche, portano i geopolimeri a essere materiali interessanti per diverse applicazioni: matrici per refrattari ed antifiamma, materiali da costruzione e restauro, matrici per l'inertizzazione di rifiuti tossici e radioattivi ecc. Il basso impatto ambientale dovuto alle materie prime e al processo a freddo necessario per il loro ottenimento li rendono ecosostenibili. Il testo si rivolge sia ai tecnologi industriali dei materiali, sia ai ricercatori che lavorano nelle università e nei centri di ricerca, proponendo una aggiornata numerosità di applicazioni.
