Scarcity and increasing cost of river sand due to large scale depletion of river bed has created a huge demand for alternative form of fine aggregate in preparation of concrete by the construction industry and builders. Several non-conventional resources such as stone dust, fly ash, carbonated sand, copper slag etc. with higher percentage of silica (SiO2) have been tried out as a substitute to river sand as fine aggregate in concrete preparation. Out of these non-conventional materials, copper slag is one such industrial waste, which is produced during the metal smelting process of copper production. Few studies have indicated that it can be suitably used as one of the major component of green concrete contributing towards reducing CO2 emission from concrete. As part of this research, experimental studies have been conducted to study various strength and durability aspects of copper slag admixed concrete and outcome on strength properties of concrete by partially replacing river sand with copper slag has been promising, also the optimum percentage of copper slag has been established as 40% for partial replacement of sand. However to prove copper slag as a building material it is imperative to study the durability aspects of copper slag concrete as well. This paper presents the mechanical properties and durability properties of copper slag concrete. An attempt has been made to find the optimum percentage of copper slag for partial replacement of sand in preparation of concrete from strength perspective. From durability perspective, effect of elevated temperature and acid attack on copper slag concrete have been presented. The results show that copper slag concrete has an excellent strength and durability properties compared to normal concrete and can be effectively utilized as a partial replacement of fine aggregate in preparation of green and sustainable concrete.
