Sustainability and resource efficiency are becoming increasing important issues within today’s construction industry. This research study reports the potential use of copper slag and foundry sand as a replacement for sand in concrete mixes. Many countries are witnessing a rapid growth in the construction industry, which involves the use of natural resources for the development of infrastructure. This growth poses a threat to natural resources that are available. Copper slag is considered as waste material and can be used as replacement of fine aggregates. The possibility of substituting natural fine aggregate with industrial by-products such as waste foundry sand and bottom ash offers technical, economic and environmental advantages which are of great importance in the present context of sustainability in the construction sector. The research study investigated the effect of copper slag as partial replacement of fine aggregates in various percentages, on concrete propertiessuch as mechanical (compressive strength, splitting tensile strength and flexural strength), modulus of elasticity and durability characteristics of the concrete. For this dissertation work, we design the mix by IS recommended guidelines. In this project, concrete ingredients are use by locally available materials. However to understand the behaviour of this copper slag replaced with fine aggregate in fresh & hardened stage of concrete, the Concrete specimens were tested at different age level for properties of concrete, namely Compression test, Flexural strength test, Acid attack test, RCPT (Rapid Chloride Permeability test), Accelerated corrosion test, Sorptivity, Water absorption test, Chloride attack test, Slump cone test as well different tests regarding to properties of concrete ingredients.
