andreas ehrenberg of the fehs presented research on converting electric arc furnace (eaf) slag into a hydraulic material that could be used in cement or concrete production. given that, using heidrich’s figures for example, about a third of ferrous slag production is steel slag often created in an eaf, the potential implications of this line of inquiry are important.
it has been reported that a specialty portland steel slag blast furnace slag cement (psbc) comprising 30% steel slag, 30% ggbfs, 35% cement clinker and 5% gypsum has been commercially marketed in china for more than 20 years. 9 this type of cement – though lower in early age strength and has longer setting time – has the advantage of low energy costs, lower heat of hydration, increased

the aim of the pilot-plant is a long term slag granulation test at first time with slag flows close to industrial plant sizes. in following figure a simplified flow sheet with the principle function of the step1 pilot plant is shown: figure 3: process scheme of phase 2 step1 pilot-plant
the higher the percentage of granulated slag was, the higher the density, the elastic modulus in compression and the compressive strength of the concrete were. dry shrinkage of the concrete increased by adding a greater amount of eaf granulated slag. keywords industrial by-products, electric arc furnace granulated slag, eco-sustainability, concrete
dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. heat is recovered from the slag in the following ways. as the spray of slag particles moves outwards from the atomizer, heat is lost by radiation to the vessel and by convection to the air moving through the vessel.

electric arc furnace (eaf) slag is a byproduct of carbon steel manufacturing and has been used in road construction for many years showing very good performance as asphalt aggregate. compared to natural aggregates, eaf slag aggregates present a higher density as required in special concrete applications such as heavy concrete for the coating of pipes for offshore pipelines.
electric arc furnace slag in concrete. this paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace (eaf) slag as fine and coarse aggregate. to do this, the slag obtained in the steelmaking process must be crushed and stabilized. first, a suitable mortar must be made and

cement is a global commodity, manufactured at thousands of plants. the industry is consolidating globally, but large international firms account for only 30% of the worldwide market. the principal and most visible market for cement is the construction industry in a multitude of applications where it is combined with water to make concrete. most modern civil engineering projects, office
slag waste granulation in indonesian steel plants has not been implemented, despite the facts that granulated slag has high potential to be upgraded as the additional material for portland cement. the slag of electric arc furnace (eaf) in pt. krakatau steel (ptks) has been a serious environmental problem. with the average slag production of
electric arc furnace granulated slag for sustainable concrete. crushing solid slag blocks and sieving  natural aggregate replacement is obviously economical for both the concrete producer for whom it reduces raw material utilization and for the steel industry in terms of the reduction of waste disposal the electric arc furnace slag generally used as a substitute for natural aggregate in
the chemical composition of the waste aggregates is summarized in table 1.water absorption and density of natural aggregates and slag waste were evaluated according to uni en 1097-6 ().eaf granulated slag showed higher density than natural aggregates as a consequence of their high iron content (20 ÷ 30% vs weight).hence, the higher the amount of slag was in the mix, the higher the
electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace (eaf) process. in this process steel scrap with additions of fluxes (e.g., lime[stone] and/or dolomite) are heated to a liquid state by means of an electric current. during the melting process the fluxes combine with non-metallic scrap components and […]
eafs is produced in an electric arc furnace. the slag is dark grey in colour and is characteristically harder than blast furnace slag (bfs). it has a density about 20 - 25% greater than basalt or bfs. it crushes to a cubical shape. eafs in common with most steel slags, is subject to slight dimensional expansion until it fully hydrates.
