This book presents articles from the Second International Conference on Sustainable Civil Engineering and Architecture, held on 30 October 2021 in Ho Chi Minh City, Vietnam. The conference brings together international experts from both academia and industry to share their knowledge, expertise, to facilitate collaboration and improve cooperation in the field. The book highlights the latest advances in sustainable architecture and civil engineering, covering topics such as offshore structures, structural engineering, construction materials, and architecture.

Over the past few years, concrete technology has advanced quite dramatically thanks to the use of a great variety of additives and admixtures, which have paved the way for the effective development of new-generation concrete mixtures. Among these additives and admixtures, nanomaterials used in construction materials such as paste, mortar, and concrete mixtures have become very popular recently. Much of the previous attention in regard to the utilization of nanomaterials in construction materials was specifically devoted to the characterization of their fresh-state, hydration, microstructure, pore structure, mechanical, transport, and durability properties. However, research into the tailoring of multi-functional properties of construction materials (especially cementitious) with the use of nanomaterials is still in its infancy. Recent Advances in Nano-Tailored Multi-Functional Cementitious Composites aims to capture recent major scientific advances and the current state of the art in multi-functional cementitious composites developed with nanomaterials. The book will provide researchers, engineers, and other stakeholders with an insight into future directions of multi-functional capabilities of cementitious composites. Chapters focus on the large-scale development, characterization, and application of multi-functional cementitious composites addressing the following topics: nano-modified concrete; strain-hardening cementitious composites; self-sensing concrete; self-healing and bacteria-based concrete; self-cleaning concrete; self-consolidating concrete; material/construction technology for 3D printing; thermal insulation capability; green concretes including geopolymer concrete; nanoscale characterization methods; low CO2 reactive magnesia cements; and future developments and challenges of nano-tailored cementitious composites. The book will be an essential reference resource for academic and industrial researchers, materials scientists, and civil engineers working on the development and application of nano-tailored multi-functional cementitious composites. Provides very comprehensive and unique details about multi-functional properties of cementitious composites Presents a detailed account of investigations conducted into the application of nanomaterials and nanoscale tailoring to achieve multi-functional properties for cementitious composites Features state-of-the-art preparation, production, processing, and implementation techniques of nanoscale tailoring of multi-functional cementitious composites starting from laboratory to large scale

Papers from The American Ceramic Society's 31st International Conference on Advanced Ceramics and Composites, held in Daytona Beach, Florida, January 21-26, 2007. Includes papers on porous ceramics ranging from nanoporous to macroporous systems, including foams, honeycombs, 3D scaffolds, interconnected fibers, sintered hollow spheres, and aerogels; ceramics in medical applications; and geopolymers, a new class of totally inorganic, aluminosilicate-based ceramics that are charge balanced by group I oxides (i.e., Na, K, and Cs)

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, nanostructure/microstructure of metakaolin and fly ash geopolymers, and geopolymer synthesis kinetics. Part two reviews the manufacture and properties of geopolymers including accelerated ageing of geopolymers, chemical durability, engineering properties of geopolymer concrete, producing fire and heat-resistant geopolymers, utilisation of mining wastes and thermal properties of geopolymers. Part three covers applications of geopolymers with coverage of topics such as commercialisation of geopolymers for construction, as well as applications in waste management.With its distinguished editors and international team of contributors, Geopolymers: structure, processing, properties and industrial applications is a standard reference for scientists and engineers in industry and the academic sector, including practitioners in the cement and concrete industry as well as those involved in waste reduction and disposal.
