Abstract
Sustainability is now commonly referred to in the construction sector, zero waste scenarios are frequently floated, a great deal of research has been undertaken in the use of recycled and secondary materials (RSM) and standards and specifications are becoming more sympathetic to their adoption; however, a clear view of the potential for the use of RSM and how this may affect performance remains to be established. This is important and needed to absorb RSM within the present hierarchy of construction materials.
The use of RSM requires a clear understanding of their characteristics and their potential for use in required applications. This can be problematic as the variability of the material can be high, though this is not unusual, as well-established materials such as Portland cement, naturally occurring sand and gravel and crushed-rock aggregates are also known for their high variation at individual plants and even more so between plants. Material processing and design procedures can help to minimise variability. Why then is the construction industry slow to adopt the use of the new breed of waste materials, such as recycled aggregates arising from demolition and excavation waste, copper slag from metal extraction processes, incinerated bottom ashes from municipal solid waste and sewage sludge and glass cullet from used domestic and industrial waste? It can be argued that the inertia in accepting the use of RSM is due mainly to two reasons: first, research has not come together to exploit the present knowledge of RSM and their potential use and, second, a robust case for the value-added use of RSM has not yet been made.
This book, as part of a series of five, brings together the global research information published in English that deals with sewage sludge ash production and properties and its potential for use as cement and aggregate in concrete, ceramics, geotechnical and road pavement applications, including related case studies, standards and environmental impacts. The data analysed and evaluated for the book were sourced from 525 publications contributed by 1107 authors, from 442 institutions in 48 countries, over a time period from 1970 to 2016.
The main purpose of the book, which is aimed at academics, researchers, design engineers, specifiers and contractors and is structured in an incisive and easy to follow manner, is to bring out what is known, how the material can be potentially used, and at the same time, avoid unnecessary repetitive research and wasting of resources.
In completing this work, the authors gratefully acknowledge the help of many individuals at different stages of the work, but would like particularly to thank Edwin Trout of the Concrete Society, UK, for his help with sourcing of the literature and Chao Qun Lye for his help with the preparation of this book.
