Utilization of Eaf Metallurgical Slag in “green” Belite Cement

چکیده
În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Analiza clincherelor s-a făcut prin microscopie optică, SEM şi XRD. Cimenturile au fost testate în conformitate cu cerinţele standardului EN 196-1. Rezultatele au demonstrate că în toate cazurile, grăunţi belitici tip I au fost stabilizaţi în urma răcirii rapide. Ambele cimenturi cu zgură, au prezentat rezistenţă scăzută la compresiune în primele zile de hidratare comparativ cu cimentul de referinţă.

A Study on Suitability of EAF Oxidizing Slag in Concrete: An Eco-Friendly and Sustainable Replacement for Natural Coarse Aggregate
Environmental and economic factors increasingly encourage higher utility of industrial by-products. The basic objective of this study was to identify alternative source for good quality aggregates which is depleting very fast due to fast pace of construction activities in India. EAF oxidizing slag as a by-product obtained during the process in steel making industry provides great opportunity to...
متن کاملEffect of aging on Phosphorus removal of metallurgical slag and heat reactivation of aged slag
In order to examine the effect of ageing on P removal capacity, the phosphorus (P) removal capacity of three types of slag, argon oxygen decarburisation slag (AOD), blast furnace slag (BFS) and electric arc furnace slag (EAF), was examined after 0, 10, 13 and 19 months in batch experiments. The results showed that ageing reduced P removal capacity, e.g. by 78.4% for 19-month-old AOD slag. For B...
متن کاملOvercoming bureaucratic obstacles to the re - use of metallurgical slag – A South African case study
Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...
متن کاملUtilization of Soil Stabilization with Cement and Copper Slag as Subgrade Materials in Road Embankment Construction
In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...
متن کاملThe effective parameters on thermal recovery and reduction of iron oxides in EAF slag
Steelmaking slag of Mobarakeh Steel Company (MSC) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. On the other hand, EAF slag in this company is almost free of zinc because of using more than 90 percent DRI in the charge. Therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. In...
