UNLV Theses, Dissertations, Professional Papers, and Capstones

Ground granulated blast furnace slag (GGBFS), a by-product from steel production, has been used as a partial replacement of portland cement in concrete for over a century. It constitutes a beneficial reuse of a by-product material, less consumption of portland cement concrete. Lower consumption of portland cement concrete can help reduce construction cost. Furthermore, it lowers the industrial carbon footprint, and landfill disposal which is a major environmental issue the world is facing today. The chemical composition of GGBF slag is similar to portland cement with hydraulic properties and additional pozzolanic properties with excellent alkali silica reactivity mitigation and resistance …
