Abstract:
Natural resources, including materials, water, energy and fertile land, are the basis for our life on Earth. However, humanity's rapidly growing consumption of these resources is causing severe damage. According to the Brundtland Report, sustainable development is a development that meets the needs of the present time without compromising the ability of future generations to meet their own needs. One of the ways to achieve sustainable development is the reuse of waste industries.Concrete is one of the most widely used material in the world. Due to greenhouse gas emissions originating from cement production and excessive using of natural aggregates, the concrete industry become one of two largest producers of carbon dioxide (CO2), creating up to 5% of worldwide man-made emissions of this gas. Therefore, in recent decades, researchers tend to use industrial waste in concrete and reduce the amount of cement in concrete mixture.Copper slag is a by-product obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date all over the world and also in Iran. This waste material can be utilized as a substitute for fine aggregate.
