Steelmaking is an energy-intensive process that generates considerable amounts of by-products and wastes, which often pose major environmental and economic challenges to the steel-making industry. One of these by-products is steel dust that is produced during the separation of impurities in the smelting and refining of metals in steel-making furnaces. In this study, electric arc furnace (EAF) dust has been evaluated as a potential, low-cost additive to increase the viscosity and weight of drilling muds. Currently, the cost of drilling operations typically accounts for 50 to 80% of the exploration costs and about 30 to 80% of the subsequent field development costs. Utilization of steelmaking waste in drilling fluids formulations is aimed to produce new and optimized water-based drilling formulations, which is expected to reduce the amount of bentonite and other viscosifier additives used in the drilling formulations. The results showed that in a typical water-based drilling fluid of 8.6 ppg (1030.51 kg/m3), the amount of standard drilling grade bentonite could be reduced by 30 wt.% with the addition of the proposed new additive to complete the required mud weight. The mixture proved to be stable with no phase separation.

O objetivo deste artigo é identificar as alterações reológicas devido ao envelhecimento a curto prazo em ligantes asfálticos aditivados com resíduo da mineração do cobre sulfetado, pois vislumbra-se a adição do resíduo ao ligante asfáltico na região amazônica em função do grande volume de produção deste tipo de rejeito. Os resultados mostraram diferenças insignificantes das amostras com e sem resíduo, inclusive para ensaio de MSCR que resultou em ligantes resistentes ao tráfego padrão, podendo suportar volume de 10 milhões de eixos padrões durante a vida de projeto.

“…The use of secondary and waste materials, slag and dross materials, to substitute certain parts of asphalt mixes is not a novelty in the past decades with a constant pursuit for a better sustainable environment, and asphalt industry [16,17,18]. Research has shown that the use, instead of disposal, of such byproducts may be a promising way, amongst others, having at least no negative effects on performance while solving part of some issues related to the accessibility of virgin materials [19,20].…”

Asphalt industry finds itself battling ongoing economic difficulties and an urge to achieve a more sustainable development and growth. it means constant searching is needed for alternative materials and possibilities to use recycled and processed waste materials in asphalt mixes as long as an expected level of performance and durability is provided. Aluminium dross is a recyclable by-product of the casting process of melted aluminium. in this study an attempt was made to reveal the potentials of using aluminium dross as filler for asphalt wearing course mixes. During the research, filler fractions (d<0.063 mm) were prepared by milling and microstructural tests were conducted both on the alternative and control filler for a better understanding of the materials and their composition. the effect of replacing limestone filler with aluminium dross filler on the performance of asphalt mixes was analysed by performance-based and performance related asphalt mechanical tests according to common standards. in the paper, the properties of fillers and various mechanical test results are presented and by interpreting the tests and results final conclusions are presented regarding the use of aluminium dross as filler in asphalt mixes. keywords: asphalt, aluminium dross, filler, rheology, stiffness kulcsszavak: aszfalt, alumínium salak, töltőanyag, reológia, merevség member of the member of the Hungarian scientific Association for transport bella UDvarDi, bSc Graduated in 2017 as material engineer, Bsc. currently working on her msc diploma work.
