Abstract

The effect of copper slag on the chloride resistance of Type IP cement concrete has not been established. The objective of this study is to determine the chloride resistance of Type IP cement concrete with varying percent replacements of copper slag. Specifically, it aims to determine the optimum copper slag percent replacement which will yield the lowest chloride depth. Seven sets of specimens with percent replacements of 0, 20, 40, 50, 60, 80 and 100% were made with a water-to-cement ratio of 0.55, and were subjected to curing period of 28 days and exposure to 3% NaCI solution of 30 days. Chloride penetration depth were measured using AgNO₃₋based colorimetric method. . results from the experiment showed that 20% copper slag in replacement of fine aggregates yielded the lowest chloride penetration depths while higher percents replacements yielded higher chloride penetration depths compared to the control specimen, which are consistent with existing studies with type I cement. These may be primarily due to physical characteristics f copper slag that contributed to bleeding and segregation, which resulted to more void spaces in the concrete matrix. The supply concluded that using small amounts of copper slag as replacement for fine aggregates increased the chloride resistance of Type IP cement concrete.
