Abstract

The primary objective of this study is to explore the potential of iron slag and copper slag as alternatives to traditional sand in concrete, with an emphasis on assessing the impact on flexural strength. This investigation experimented with three distinct mixtures: a combination of cement with iron slag and copper slag, a blend of cement with sand and iron slag, and a mixture of cement with sand and copper slag. The study varied the proportions of the combinations and the duration of curing, which included intervals of 7, 28, 56, and 90 days, to serve as independent variables. The experimental results suggested that a mixture of iron slag and copper slag in a ratio of 40:60, in conjunction with cement, yielded the most promising results, with an enhancement in flexural strength of up to 92% observed over the 90-day curing period compared to the initial 7-day strength measurement. The findings from this research offer valuable insights into the utilization of waste materials in the construction industry, addressing crucial concerns related to environmental sustainability and solid waste management. The implications of this study extend beyond mere technical outcomes, emphasizing the need for innovative approaches in the construction sector that contribute to ecological conservation and waste reduction.
