Copper slag is a by-product created during the copper smelting and refining process. The specific gravity varies with iron content, from 2.8 to 3.8. For every ton of copper production, about 2.2 tons of copper slag is generated. 3 0 obj The bending properties of the composite were performed using the three-point bending test. Copper slag, which is the waste material produced in the extraction process of copper metal in reﬁnery plants, has low cost and its application as a ﬁne aggregate in concrete production have many environmental beneﬁts such as waste recycling and solves disposal problems. The slag serves as a fine, or binding agent, which helps hold the larger gravel particles within the concrete together. Copper slag which is an industrial waste product can be used as replacement for cement with sand and contributes to the increase in various mechanical properties of concrete. A typical smelting slag contains approximately 30–45% FeO, 30–40% SiO2, 5–10% Al 2 O 3, 2–6% CaO, and 2–4% MgO (Kokal, 2006). It has been estimated that approximately 24.6 million tons of slag are generated from the world copper industry. The unit weight of copper slag is somewhat higher than that of conventional aggregate. Table 3.2 presents the wide-range chemical composition of copper slag from different sources. The results indicate that granulated blast furnace slag conforms to all the requirements of Indian Standard Specification IS: 12089-1987 for the manufacture of PSC unlike copper slag. 77, No. Air-cooled and quenched slags are the outcomes of different cooling rates applied during the production of copper.

The results of laboratory tests on this slag have been compared with the representative values obtained for sands. Copper slag is mainly used for surface blast-cleaning. An environmental risk assessment (leaching and solubilization testes) showed that copper slag does not pose any risks to human health or to the environment, thus being classified as noninnert. 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. 3.4. When used in this manner, the slag helps to improve the properties of the concrete, and also serves as a form of recycling.
