Abstract

The present study encourages the use of waste materials copper slag (CS) and fly ash (FA) as supplementary cement replacement materials in concrete. The combined effect of copper slag and fly ash as a partial replacement of cement on flexural strength of concrete has been investigated. Fifteen mixes were prepared at different replacement levels of copper slag (0 to 20% @ increment of 5%) and fly ash (0 to 10% @ increment of 5%) with cement. Three prisms (150 mm X 150 mm X 700 mm) were casted and tested after 7 and 28-days of curing to determine the flexural strength (modulus of rupture) for each mix. It was observed that the flexural strength of concrete decreases as copper slag content increases for all curing ages. The reduction in flexural strength was minor (4.30% to 7.60%) up to 10% of copper slag but beyond 10% of copper slag, there was significant reduction (24.70% to 34.21%) in flexural strength. The addition of 5% and 10% fly ash with copper slag slightly reduced the flexural strength.
