Potential use of alternatives to primary aggregates in coastal and river engineering

This review seeks to identify the potential for using secondary and recycled aggregates, including inert construction and demolition (C&D) waste, in coastal and river engineering schemes. In response to concerns about the environmental consequences and long-term sustainability of the present rate of use of primary aggregates, guidance is offered on employing alternative materials and so reducing the impact of river and coastal construction on natural resources. The book begins by reviewing the types of river and coastal engineering schemes that exist around the UK and the materials used in them. The various alternatives to primary aggregates available in the UK - such as secondary aggregates and recycled inert C&D waste - are described, along with some of the environmental and practical engineering issues that arise in their use. Guidelines on using these alternative materials are supported by numerous case studies. The book concludes with recommendations for future research and development, and a directory of suppliers and sources of further information.
