Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.

Aggregate Resources provides a comprehensive collection of 27 diverse scientific papers on aggregate topics, such as geology of deposits, geophysical exploration techniques, deposit prediction and modeling, land-use case studies, production values and trends, geotechnical properties, legislation politics and others. This diversity in subject matter is further enhanced by relying on contributions from a number of countries including Australia, Belgium, Canada, Lebanon, the Netherlands, Norway, South Africa, the United Kingdom and the United States. The range of topical papers and representative countries, coupled with the global significance of the resources prompted the title Aggregate Resources: A global perspective. The book will appeal to all those involved with aggregate resources: geologists, producers, technicians , construction engineers, developers, land-use planners, legislators, academics and the public consumer, especially since all of us are in some manner, directly dependent or indirectly affected by this resource. *Each chapter is a study on a particular area of importance for aggregate producers.

The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste

This Phase II investigation of the durability of new concrete containing recycled concrete aggregates (RCA) sought to corroborate Phase I results for a study of alkali-silica reactivity (ASR), investigate ASR mitigation methods, gather long-term outdoor placement data, and survey transportation agencies about their RCA perceptions and usage. Findings show the ASTM coefficient of variation limits do not apply when incorporating RCA. We recommend further testing to establish new standards.The survey showed sustainability was important to most agencies; 54%% had guidance for RCA use in new concrete, but only 15%% reported strong federal guidance; 77%% had concerns about ASR reaction; the biggest barriers to RCA use were quality issues, lack of standards, and unclear test guidance; the biggest RCA source concerns were shrinkage, ASR and residual chlorides. Data sought on RCA sources were condition at removal from service, reason for removal, whether the original structure needed repairs, and material age.
