Study on partial replacement of sand with foundry sand and copper slag

Copper slag is considered as a one of the component of an industrial waste. This paper presents the impact of concrete as a fine aggregate substitute using foundry sand and copper slag.M20 grade of concrete was selected and IS methods have been used for designs. Foundry sand and copper slag properties has been studied for mix design. The different strength of concrete such as compressive are tested for different fine aggregate replacements using 0%, 15% and 30% foundry sand and copper slag. The maximum compressive strength of concrete was reached when the fine aggregate was replaced by 15% at 7 and 28 days. Making concrete from recycle materials saves energy and resource conservation which contributes to safe sustainable environment.
