Covering the latest technologies, Nanotechnology in eco-efficient construction provides an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction. The book contains a special focus on applications concerning concrete and cement, as nanotechnology is driving significant development in concrete technologies. The new edition has 14 new chapters, including 3 new parts: Mortars and concrete related applications; Applications for pavements and other structural materials; and Toxicity, safety handling and environmental impacts. Civil engineers requiring an understanding of eco-efficient construction materials, as well as researchers and architects within any field of nanotechnology, eco-efficient materials or the construction industry will find this updated reference to be highly valuable.

As the environmental impact of existing construction and building materials comes under increasing scrutiny, the search for more eco-efficient solutions has intensified. Nanotechnology offers great potential in this area and is already being widely used to great success. Nanotechnology in eco-efficient construction is an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction.
Following an introduction to the use of nanotechnology in eco-efficient construction materials, part one considers such infrastructural applications as nanoengineered cement-based materials, nanoparticles for high-performance and self-sensing concrete, and the use of nanotechnology to improve the bulk and surface properties of steel for structural applications. Nanoclay-modified asphalt mixtures and safety issues relating to nanomaterials for construction applications are also reviewed before part two goes on to discuss applications for building energy efficiency. Topics explored include thin films and nanostructured coatings, switchable glazing technology and third generation photovoltaic (PV) cells, high-performance thermal insulation materials, and silica nanogel for energy-efficient windows. Finally, photocatalytic applications are the focus of part three, which investigates nanoparticles for pollution control, self-cleaning and photosterilisation, and the role of nanotechnology in manufacturing paints and purifying water for eco-efficient buildings.
Nanotechnology in eco-efficient construction is a technical guide for all those involved in the design, production and application of eco-efficient construction materials, including civil engineers, materials scientists, researchers and architects within any field of nanotechnology, eco-efficient materials or the construction industry.

Handbook of Low Carbon Concrete brings together the latest breakthroughs in the design, production, and application of low carbon concrete. In this handbook, the editors and contributors have paid extra attention to the emissions generated by coarse aggregates, emissions due to fine aggregates, and emissions due to cement, fly ash, GGBFS, and admixtures. In addition, the book provides expert coverage on emissions due to concrete batching, transport and placement, and emissions generated by typical commercially produced concretes.

3D Concrete Printing Technology provides valuable insights into the new manufacturing techniques and technologies needed to produce concrete materials. In this book, the editors explain the concrete printing process for mix design and the fresh properties for the high-performance printing of concrete, along with commentary regarding their extrudability, workability and buildability. This is followed by a discussion of three large-scale 3D printings of ultra-high performance concretes, including their processing setup, computational design, printing process and materials characterization. Properties of 3D-printed fiber-reinforced Portland cement paste and its flexural and compressive strength, density and porosity and the 3D-printing of hierarchical materials is also covered.

Nowadays, most industrial slags are being used without taking full advantages of their characteristics or disposed rather than used. Ground granulated blast furnace has been used for many years as a supplementary cementitious material in Portland cement concrete. This waste material typically replaces 35-65% Portland cement in concrete. Thus a 50% replacement of each ton of Portland cement would result in a reduction of approximately 500,000 t of CO2. On the other hand, using nanoparticles in concrete specimens is a relatively new concept which was proceeds over the past decade. In the present work, nanoparticles have been added to concrete specimen containing high volume ground granulated blast furnace to enhance their physical and mechanical properties. In the other words, nanotechnology and waste management have assisted each other to produce high strength green concrete.

In This book, Charpy impact energy of functionally graded steels produced by electroslag remelting been modeled analytically and numerically. To build the models, the yield stress of each graded layer has been related to its density of dislocations through mechanism-based strain gradient plasticity theory and then by assuming Holloman relation for the corresponding stress-strain curve of each layer, tensile strength and tensile strain of the constituent layers were determined via numerical method. In addition, a modification method for taking into account the strain rate has been proposed. The Charpy impact energy of each layer has been related to the corresponding area under modified and un-modified stress-strain curve of that layer and finally by applying the rule of mixtures, the Charpy impact energy of the specimens has been modeled analytically. In addition, finite element simulation has been conducted and the input data are the predicted modified and un-modified stress-strain curve data. All of the proposed models have shown good agreement with the experimental results.

Achieving high performance engineering materials needs deep insight to the application of the related materials. High strength self compacting concrete could be one of the most important structural components in our life. Production of these materials could increase the durability and life time of the related equipments. One of the additive materials to cement paste to achieve this aim is nanoparticle. In this book, strength assessments and water permeability in terms of coefficient of water absorption of high performance self compacting concrete containing different amount of Al2O3 nanoparticles have been investigated. Strength and the resistance to water permeability of the specimens have been improved by adding Al2O3 nanoparticles in the cement paste up to 4.0 weight percent. In addition, some models based on fuzzy logic (FL) and adaptive network-based fuzzy inference systems (ANFIS) have been presented to predict the effects of Al2O3 nanoparticles on compressive strength of the specimens. FL and ANFIS were found to be capable to predict the compressive strength of the specimens very close to the experimental data.
