Abstract:Concrete is one of the prime materials for construction and it is the most broadly utilized for different applications everywhere throughout the world. Aggregate makes 70% of its volume is the principal component material in concrete production and consumes globally 8–12million tonne of natural aggregate annually. The accumulated waste generated from industries severely affects environmental conditions. The reuse of industrial waste materials and by – products also decreases the need to produce new raw materials. The scarcity of raw materials required for construction is increasing day by day due to globalization. The main challenge for researchers and engineers is preventing the exhaustion of natural resources and increasing the usage of waste materials. The fact that materials that consider as waste from different industries are expanding and Increasing to cover the huge demand of construction materials and existing structure restoration, as the Engineers especially civil engineers has left a big impression throughout the history that consider an Ecological move via using new waste materials in the construction and development. Due to its mechanical strength, porosity, wear resistance and water absorption, steel slag is already being used as a fine and coarse aggregate for asphalt road mixes, as well as a raw material for clinker, as ballast for railways, and as a filling material in various excavations. Successful incorporation of steel slag as aggregates in construction products requires the consideration of certain issues. Firstly, as steel slag is an industrial by product until recently disposed in landfills, the question is whether it is suitable for use in construction. Then the technical characteristics of the material are examined because due to its physicochemical properties steel slag requires special care, but can also provide maximum value if used for specific applications. The utilization of a by-product in suitable applications mainly where it is advantageous compared to traditional materials, but also where it is most economical can give a higher added value to the product. Finally, there are a number of economy-related parameters that allow for a new product to enter the construction market like the situation of the local aggregate market or the need to communicate the efficiency of a new product through demonstration projects. This study aims to analyze the viability of the use of waste products (silico manganese slag) from low carbon silico manganese industry as coarse aggregate in concrete.
