This book focuses on civil engineering materials and nanotechnology. Highlighting recent advances in the field of nano-engineered cementitious composites, it discusses their key principles, design and fabrication, testing and characterization, performance and mechanisms, as well as applications. Future developments and remaining challenges are also outlined. Nano-engineered cementitious composites are exceptionally strong, durable and offer multifunctional/smart performance that differs considerably from that of normal cementitious composites. Providing valuable insights into these composites’ future development, the book offers an essential source of information, inspiration, theory and practical guidance for developing sustainable cementitious composites. As such, it will benefit researchers, scientists and engineers in the fields of civil engineering materials and nanotechnology alike.

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

Engineered cementitious composites (ECC) is a new type of fiber-reinforced bendable cementitious composite that is used in various civil engineering applications instead of conventional and fiber-reinforced concrete due to its high mechanical and durable properties. In the macro and micro mechanic systems of ECC, the incorporation of different materials plays a vital role in enhancing the properties of ECC. Conventional concrete and fiber-reinforced concrete have a brittle nature and crack easily under environmental and mechanical loads, affecting the durability of structures. The usage of alternative materials in the ECC modifies the brittle nature and offers environmentally sustainable construction with low embodied energy and a negative carbon footprint. Production, Properties, and Applications of Engineered Cementitious Composites highlights the new and innovative ways of production, properties, and various applications of engineered cementitious composites. The main focus of the book is on the latest advancements, technical knowledge, tools, and solutions for engineered cementitious composites manufacturing, design, and technologies for construction from various perspectives. Covering key topics such as alternative materials, mineral admixtures, and testing of engineered cementitious composites, this premier reference source is ideal for engineers, industry professionals, researchers, academicians, scholars, practitioners, instructors, and students.

The 3rd International Symposium on Nanotechnology in Construction (NICOM 3) follows the highly successful NICOM 1 (Paisley, UK 2003) and NICOM 2 (Bilbao, Spain 2005) Symposia. The NICOM3 symposium was held in Prague, Czech Republic from May 31 to June 2, 2009 under the auspices of the Czech Technical University in Prague. It was a cross-disciplinary event, bringing together R&D experts and users from different fields all with interest in nanotechnology and construction. The conference was aimed at: Understanding of internal structures of existing construction materials at nano-scale Modification at nano-scale of existing construction materials. Production and properties of nanoparticulate materials, nanotubes and novel polymers. Modeling and simulation of nanostructures. Instrumentation, techniques and metrology at nano-scale. Health and safety issues and environmental impacts related to nanotechnology during research, manufacture and product use. Review of current legislation. Societal and commercial impacts of nanotechnology in construction, their predictions and analysis.

An important new state-of-the-art report prepared by RILEM Technical Committee 108 ICC. It has been written by a team of leading international experts from the UK, USA, Canada, Israel, Germany, Denmark, South Africa, Italy and France. Research studies over recent years in the field of cement science have focused on the behaviour of the interfaces between the components of cement-based materials. The techniques used in other areas of materials science are being applied to the complex materials found in cements and concretes, and this book provides a significant survey of the present state of the art.
