USE OF MINING AND METALLURGICAL WASTES IN CONSTRUCTION.
Trends in the utilization of mining and metallurgical waste in construction have been determined from general waste recycling surveys of North American and British construction agencies, supplemented by literature surveys. This information is being incorporated into a data bank on waste utilization that is continually updated. In some cases laboratory studies on particularly promising secondary products and wastes, such as taconite tailings, slags, spent pickle liquors, fly ashes, waste limes, etc. , have been conducted. Some of these studies, and other examples of potential waste recycling in construction, are presented to indicate the trends in utilization, some of the techniques developed for particular applications, the general economics involved and requirements for future research.
