The Utilization of Slag in Civil Infrastructure Construction

Book excerpt: The Utilization of Slag in Civil Infrastructure Construction strives to integrate the theory, research, and practice of slag utilization, including the production and processing of slags. The topics covered include: production and smelting processes for metals; chemical and physical properties of slags; pretreatment and post-treatment technology to enhance slag properties; potential environmental impact; mechanisms of potential expansion; special testing methods and characteristics; slag processing for aggregate and cementitious applications; suitability of slags for use in specific applications; overall properties of materials containing slags; and commercialization and economics. The focus of the book is on slag utilization technology, with a review of the basic properties and an exploration of how its use in the end product will be technically sound, environment-friendly, and economic. - Covers the production, processing, and utilization of a broad range of ferrous, non-ferrous, and non-metallurgical slags - Provides information on applicable methods for a particular slag and its utilization to reduce potential environmental impacts and promote natural resource sustainability - Presents the overall technology of transferring a slag from the waste stream into a useful materials resource - Provides a detailed review of the appropriate utilization of each slag from processing right through to aggregate and cementitious use requirements
