Potential Reuse of Electric-Arc Furnace Dust (EAFD) in Concrete
This study investigated electric arc furnace dust (EAFD) reuse as a raw material in concrete mixes. A comprehensive experimental program consisting of two phases of testing was carried out. The first phase included the replacement of ordinary Portland (Type I) cement by unsieved dust with the percentages of 0, 2.5, 5, 7.5 and 10%. The second phase included the replacement of quartz (filler) by ...
متن کاملElectric Arc Furnace Slag and Blast Furnace Dust, Use for the Manufacture of Asphalt Concrete for Roads
This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...
متن کاملMethod and Mechanisms of Soil Stabilization Using Electric Arc Furnace Dust
This paper reports the method and mechanism for improving the strength of marl and desert sand utilizing electric arc furnace dust (EAFD), an industrial by-product, in lieu of cement or lime. EAFD was used in conjunction with a small quantity (2%) of cement. The mechanical properties and durability characteristics of marl and sand mixed with 2% cement plus 5-, 10-, 20- or 30%-EAFD, by weight of...
متن کاملInvestigation of Possible Usage of Electric Arc Furnace Dust in Cement Industry
Synopsis-In this research, possible usage of EAF dust on cement is investigated. Therefore, effects of addition of different percentages of EAF dust on the most important properties of cement such as hydration heat, water coefficient, viscosity, initial and final setting times, strength development and leachability of heavy metals were studied. Results showed that EAF dust alters the characteri...
متن کاملA KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST
In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...
