Steel making slag is the process for producing steel from iron or scrap. Modern steelmaking processes can be broken into two categories: primary and secondary steelmaking. Secondary steelmaking is most commonly performed in ladles and often referred to as ladle. The main by-product of this process is ladle furnace slag (LFS). In this paper self-compacting concrete (SCC) mixtures were produced, in which, filler was replaced by LFS. Three different strength classes were tested and LFS was used in different contents ranging from 45 to 92.5 kg/m(3). SCC mixtures were tested in the fresh state for fluidity, passing ability and resistance to segregation. In the hardened state these mixtures were tested for compression strength, resistance to carbonation, sorptivity, resistance to chloride penetration and to freeze-thaw. The results concluded that, LFS enhances the durability characteristics of concrete leading to environmentally friendly concrete mixtures with lower cost. (C) 2018 Elsevier Ltd. All rights reserved.
