Concrete technology for a sustainable development in the 21st century focuses on the problems and challenges for the concrete industry today and in the future with particular emphasis on environmental consiousness. Primary topics include: the improvement of concretes service life to ease technical and economical problems and the waste of natural resources; environmentally friendly concrete production including new production methods and recycling materials; and actually using concrete to solve environmental problems, for example through the containment of hazardous waste. The book is the result of the international workshop held in Lofoton, Norway. With very select contributions from the most distinguished international professional experts, this book provides a basic framework and guidelines for national and international bodies.

Production of Portland cement is responsible for about seven percent of the world’s greenhouse gas emissions. The pressure to make the production of concrete more sustainable, or "greener", is considerable and increasing. This requires a wholesale shift in processes, materials and methods in the concrete industry. Pure Portland cement will need to be replaced by more complex binary, tertiary or even quaternary binders, including other types of cementitious materials. We can expect an increasing use of high performance concrete, primarily because of its high sustainability and durability. Much more attention will have to be paid to the proper curing of the concrete if we want to improve its life expectancy. Presenting the latest advances in the science of concrete this book focuses particularly on sustainability, durability, and economy. It explores the potential for increased sustainability in concrete from the initial mixing right through to its behaviour in complex structures exposed to different types of loads and aggressive environments.

Concrete is the most widely-used construction material in the world. This important book summarises the wealth of recent research on improving qualities such as durability and sustainability as well as the emergence of a new generation of specialist concretes for particular applications. A number of chapters discuss new types of concrete such as autoclaved aerated concrete, high-strength concrete, sprayed concrete, fibre-reinforced concrete, lightweight concrete, self-compacting concrete, foamed and polymer concrete, together with their characteristics and applications. Other chapters review the development of concrete especially suited for particular conditions such as radiation protection, hot weather and underwater conditions, as well as the increasingly important area of recycling. With its distinguished editor and international team of contributors, Developments in the formulation and reinforcement of concrete is a standard reference for civil and structural engineers. Summarises a wealth of recent research on improving qualities such as sustainability and durability Discusses new concrete types together with their characteristics and applications Reviews the development of concrete especially suited to particular conditions such as hot weather and under water

The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.

One of the most pressing problems facing the construction industry globally is the deterioration of major concrete infrastructure in marine and other chloride-containing environments. While recent advancements in concrete technology have made it easier to control the negative impact of deteriorating processes such as alkali-aggregate reaction, freezing and thawing and chemical attack, chloride-induced corrosion of embedded steel continues to pose the biggest threat to structure durability and performance. The second edition of Durability Design of Concrete Structures in Severe Environments focuses on enhancing the durability and service life of concrete structures. The text describes field experience and deteriorating processes of concrete structures in severe environments, and includes current data based on extensive field investigations. It presents a durability design based on calculation of corrosion probability, and outlines additional protective strategies and measures. The text also describes procedures for performance-based concrete quality control and quality assurance with documentation of achieved construction quality and compliance with specified durability. The text further covers calculation of life cycle costs and life cycle assessment, and includes some new recommended job specifications. What’s New in the Second Edition: This second edition delivers more results and experience from practical applications of the probability-based durability design and the performance-based concrete quality control. It includes recent commercial projects both for Oslo Harbor KF and Nye Tjuvholmen KS in Oslo, and contains some preliminary results from the more comprehensive research program "Underwater Infrastructure and Underwater City of the Future" at Nanyang Technological University in Singapore. The book serves as an essential guide both for the owners and the consulting and construction engineers involved in new and major concrete infrastructure design and construction.

Once, civil engineers were esteemed by the public as both visionaries and leaders in a noble profession essential to the welfare of humankind. Today, though, civil engineers are often seen as mere advisors and technicians. The 21st-Century Engineer argues that this situation must change and that the means to do so are in the hands of engineers themselves. In this groundbreaking manifesto, Galloway vividly paints the new global landscape where megaprojects, sustainability, infrastructure security, and multicultural work teams pose challenges for which engineers may be unprepared. With businesslike brevity, she lays out nontechnical areas in which engineers must become proficient: globalization, communication, ethics and professionalism, diversity, and leadership. Galloway contends that the existing system for educating engineers must change, and she proposes a new master's degree in professional engineering management. A must-read for all thoughtful engineers involved in educating, hiring, and managing, The 21st-Century Engineer is a clarion call to reform the way today's engineers prepare for tomorrow.
