Abstract. In this work, we aim to prepare M30 grade concrete utilizing copper slag as a replacement material for fine aggregates in proportions of 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and in the concrete. The experiment was conducted at constant w/b and w/c ratios with varying amounts of superplasticizer, and …
