GEOTECHNICAL PROPERTIES OF A COPPER SLAG

The geotechnical properties of a copper slag are presented. The slag, produced at the American Smelting and Refining Company (ASARCO) plant in El Paso, Texas, is a by-product of refining copper ore in oil-fired reverberatory furnaces. The geotechnical properties include sieve analysis, specific gravity, maximum and minimum dry unit weights, angle of shearing resistance, one-dimensional compressibility, and permeability. The results of laboratory tests on this slag have been compared with the representative values obtained for sands. The comparison shows that the values of the slag are similar to those obtained for medium sands, and it can be used as a construction material in place of sand, such as backfill of retaining walls and landfill for construction of shallow foundations. Toxicity tests on the slag for possible groundwater pollution are also included. Based on the current U.S. Environmental Protection Agency (EPA) regulations governing solid waste characteristics, the slag can be classified as nonhazardous.
