Abstract

This research examines the environmental effects of concrete containing phosphorus furnace slag. For this purpose, the Leopold Matrix method was used as an analytical tool to identify and evaluate environmental impacts. The results obtained from the Leopold matrix analysis showed that using phosphorus furnace slag in concrete production can have significant positive effects on the environment. Based on numerical results, concrete with phosphorus slag with a score of (198) was better than ordinary concrete. These effects primarily include reduced extraction of natural resources, especially stone materials, assistance in managing industrial waste, and a decrease in environmental pollutant emissions. Concrete containing slag is presented as a more environmentally friendly option compared to conventional concrete and can be considered an effective step toward sustainable development in the construction industry. Overall, the findings indicate that replacing a portion of natural materials with recycled industrial materials is not only effective in reducing pressure on natural resources but also con-tributes to improving the environmental performance of construction projects.
