Most of these products are used as a raw material in Portland blast furnace slag cement. They are found to be useful in many fields, such as road construction, asphalt concrete, agricultural fertilizer, and soil improvement. An alternative to the use of the steel slag in the cement production is adjusting its … After 30 days, there was a very small loss of mass, but it did not reach even 0.5% at 270 days. However, it is less applied in the base course. Building construction and building operations have a massive direct and indirect effect on the environment [, Cement-based materials will remain essential to supply the growth of our built environment, mainly by those located in the developing world. At 28 days the compression strength of the REF mixture was 50 MPa [. Slag Substitution as a Cementing Material in Concrete: Mechanical, Physical and Environmental Properties. While the previous three answers are close, they don’t get the brass ring. Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. Fine sand (0/2), medium size sand (0/4) and gravel (4/12). Parron-Rubio, M.E. For comparison purposes a reference mixture without slag and mixtures with the same content of GGBFS and LFS were also prepared. Oliveira, M.J.; Ribeiro, A.B. Zhang, M.H. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser. Read more on why we use aggregates in concrete. It is speculated that the higher early strength of LFS mixtures may be related with higher CaO content of LFS, when compared to GGBS. We use cookies on our website to ensure you get the best experience. Steel slag is produced by the conversion of raw iron into steel – around 125 million tons of it per year. Disadvantages of Blast-Furnace Slag Cement Early Strength is low; therefore, it cannot be used in Reinforced Cement Concrete (RCC) works. In Proceedings of the International Conference, João Pessoa, Brazil, 24–26 November 2000; pp. W/C effects, micro–macro correlations, and threshold values. This information can be useful for minimizing the cracking of concrete elements, due to shrinkage, and improving its performance in service, contributing to the greater use of slag and to a more sustainable construction. In Early Age Cracking in Cementitious Systems, RILEM TC 181-EAS. Sustainable concrete for infrastructure regeneration and reconstruction, in Sustainable Construction into the next Millennium: Environmentally friendly and innovative cement based materials. Matthes, W.; Vollpracht, A.; Villagrán, Y.; Kamali-Bernard, S.; Hooton, D.; Gruyaert, E. Ground granulated blast-furnace slag. Available online: Tazawa, E. Autogenous Shrinkage of Concrete. Approximately 40% of iron and steel slag products, and 60% of blast furnace slag, are used in cement. Please let us know what you think of our products and services. those of the individual authors and contributors and not of the publisher and the editor(s). Study of the suitability of different types of slag and its influence on the quality of green grouts obtained by partial replacement of cement. Industrialización de Procesos Y Valoración de Residuos Siderúrgicos. [. The minimum vertical deformation was obtained in the KC cross-section where the steel slag is used in the subbase layer. MELBOURNE, AUSTRALIA, APRIL 9, 2020 --Researchers have shown how a by-product of steel making can be used to both treat wastewater and make stronger concrete, in a zero-waste approach to help advance the circular economy.Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete. The use of ground granulated blast furnace slag in concrete, as cement constituent or as latent hydraulic binder, is a current practice, but information of concrete with ladle furnace slag is more limited. Portland cement, class strength 52.5 R, was used because this cement contains 95–100% Portland cement clinker. [. Slag as in common usage is the result of the steel making process. 2-6-1 Marunouchi, Chiyoda-ku, Tokyo 100-8071 Production and Use of Blast Furnace Slag Aggregate for Concrete Takayuki MIYAMOTO* Koichi TORII Kenichi AKAHANE Sachiko HAYASHIGUCHI Abstract It has been more than 30 years since the use of blast furnace slag as concrete aggregate ; Brownyard, T.L. We use cookies to help provide and enhance our service and tailor content and ads. Background. Steel slag, which can be used as a cementitious material, is widely used in road engineering. July 2009; 27–34. However, better utilization for value-added purposes in cement and concrete products can be achieved. Swamy, R.N. In this work, five concrete mixtures were prepared, namely, a reference mixture without cement replacement and four mixtures in which 25% and 40% cement replacement (mass), using separately ground granulated blast furnace slag (GGBFS) or ladle furnace slag (LFS). ; Parron-Rubio, M.E. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. © 2018 Elsevier B.V. All rights reserved. Cement-based materials will remain essential to supply the growth of our built environment. In this paper, an overview of the recent achievements and challenges of using steel slags (BOF, EAF and LF slag) as cement replacement (usually ground into powder form with the size of 400–500 m2/kg) and aggregate in cement concrete is presented. Abstract. This paper presents the results of the shrinkage (total and autogenous) of five concrete mixtures, produced with different percentages of two different slags in substitution of cement. They are found to be useful in many fields, such as road construction, asphalt concrete, agricultural fertilizer, and soil improvement. Environmentally friendly and reduced greenhouse gas emissions Perez-Garcia, F.; Rubio-Cintas, M.D. In fact, the use of industrial and construction waste as raw materials for the production of cement and concrete can be considered not only to reduce CO, Depending on different factors, mainly due to the manufacturing process, four types of steel slag can be identified: blast furnace slag (BFS), ladle furnace slag (LFS), electric arc furnace (EAF) and basic oxygen furnace slag (BOFS) [, Shrinkage is the diminution in either length or volume of a material, after suffering changes in chemical properties or moisture content, and occurs in the absence of external actions applied to the concrete [, Standardization in the field of construction products, and in particular in the field of concrete with hydraulic binders, has been providing an increase in the quality and durability requirements of concrete structures. Slag cement is as old as iron-making itself. The swelling underwater of GGBS and LFS mixtures was similar. (1) It has high resistance to seawater and to chemicals, and can improve durability. Steel slags are industrial by-products of steel manufacturing, characterized as highly calcareous, siliceous and ferrous. They can be categorized into basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag. The iron is used to produce steel, and the molten slag is converted to a cement-like material by rapidly cooling it with water.
