EFFECT OF COPPER SLAG ON WORKABILITY AND COMPRESSIVE STRENGTH OF CONCRETE
Reduction in cement used in concrete production is an important strategy to reduce non-renewable raw materials used in cement production, such as clay, limestone, and chalk. Reducing the use of cement in the production of clinker can result in a decrease in both energy consumption and CO_2 emissions. Furthermore, the process of calcining clay, limestone, and chalk emits carbon dioxide into the atmosphere, a problem that leads to global warming. Conversely, substantial amounts of industrial and agricultural wastes, which have limited alternative use, are being generated globally. Thus, copper slag, a byproduct of the industrial process of iron production, can cause environmental problems if not properly used. To benefit from it, it should be repurposed and used in other industries. Giad industrial company in Sudan provided the copper slag (CS). This study aims to investigate the effects of the substitution of Portland cement with copper slag at dosages of 10 and 15% by weight on the fresh and compressive strength of concrete. The findings indicate that copper slag incorporated into concrete slightly improved workability while reducing compressive strength.
