“…It was well known that the steel-slag concrete improves the flexural strength [6] and that the fibers provide better deformation performance by flexion [49] The results were similar to the previous ones of compressive strength, reaching the best results the mixtures EM2 and ES1. Fig.…”

“…So, an outdoor weathering and some additional cautions are necessary to prevent the occurrence of any expansive phenomena [2][3][4][5][6]. In the last decades, important works on EAFS [7][8][9][10] and LFS characterization [11][12][13] have been published; it has been demonstrated the suitability of both slags in different applications, such as bituminous mixtures [14][15][16][17][18], concrete and mortars [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34], selfcompacting concrete [35][36][37], making clinker [38], soil stabilization [39][40][41] and others [42,43].…”

Abstract. In this research, the possibility of making concrete reinforced with fibers and manufactured with recycled aggregates from carbon steel production was explored. Electric arc furnace slag (EAFS) was used as coarse and medium aggregate, and part of the sand sizes. Metallic and synthetic fibers were added in different amounts. Initially, the properties of EAFS and their suitability to be used in the manufacture fiber reinforced concrete were analysed. Then, a series of fiber reinforced concrete mixtures were developed incorporating EAFS, and they were compared with the reference mixtures, made with conventional components plus fibers and made with EAFS without fibers. A series of tests were performed, including concepts such as consistency, compressive strength, flexural strength, splitting tensile strength, resistance to water penetration or toughness. The results show that it is possible to make a suitable steel-slag concrete reinforced with fibers, complying with the standard requirements for it use in pavements and slab, and improving their proprieties respect to the control mixtures.

“…Since then, many published works from these and other authors have concluded that concrete manufactured with EAF slag has at least the same mechanical properties as concretes manufactured with natural materials [7,8], and of similar durability [9,10]. The disadvantages of using this raw material in the aforementioned way are its higher specific weight and the lower workability of its mixes.…”

Performing self-compacting concrete with electric arc-furnace slag as aggregates

et al. 2017

Abstract. The electric steelmaking industry is of great importance to the economy of the Basque Country (Spain). In all, 600,000 tons of electric arcfurnace (EAF) slag are produced every year; a by-product that this research group believes can be transformed into a useful resource. One of the uses of this material is as an aggregate in hydraulic mixes. Many studies have demonstrated that hydraulic mixes manufactured with EAF slag have at least the same mechanical behaviour and durability as ordinary concrete. However, their weaknesses are their higher density and poorer workability. In this paper, the aim is to demonstrate that manufacturing slag concrete to an acknowledged standard of workability is possible; so the objective is to manufacture self-compacting concrete using EAF slag in partial substitution of aggregates. Our analysis of the successful manufacture of three different self-compacting mixes, their properties in the fresh state and their mechanical behaviour yielded very encouraging results.

“…The recycling of industrial by-product as a material of concrete is an alternative way to reduce energy consumption and the emission of carbon dioxide. The steel industry generates various types of slag as industrial by-product depending on the processes (Manso et al 2004). The use of steel has gradually increased; consequently, industrial by-products have increased every year as well.…”

This study evaluates the flexural behavior of reinforced high-strength concrete beams with electric arc furnace (EAF) oxidizing slag aggregates. The main test parameters include the type of aggregates, compressive strength of concrete, and tension reinforcement ratio. A total of eight simply supported beam specimens subjected to four point loads are cast and tested in flexure. Two types of aggregates, natural and EAF oxidizing slag aggregates, are used in this study. The compressive strength of the concrete is designed to have normal-and high-strengths of 24 MPa and 100 MPa, respectively. The tension reinforcement ratios of beam specimens are 0.3 and 0.5 times the balanced reinforcement ratio for flexure. The experimental results indicated that the flexural strength of specimens was not affected by the type of aggregate, whereas the flexural ductility of specimens with EAF oxidizing slag aggregates was superior to that of specimens with natural aggregates, regardless of the compressive strength of concrete and the tension reinforcement ratio.
