Abstract: The utilization of electric-arc furnace dust (EAFD) in concrete industry has been the subject of interest of recent studies. These studies have proven that EAFD might be used in concrete to enhance its performance. In general, previous studies on the utilization of EAFD in concrete mixtures were in the form of using EAFD as a partial replacement of cement. Some promising benefits such as gain of compressive strength and better transport properties have been reported in the literature in addition to its effect on prolonging setting time. The underlying mechanisms on how EAFD affects the concrete properties are still not well understood. The purpose of this study is to investigate these phenomena through different experimental tests at both macro and microscopic levels.
Key words: EAFD, setting time, heat of hydration
