“…Samples M 3 , M 5 and M 6 showed relatively god mechanical properties. It was concluded that, in this compositions, the C 3 S developed better, sample M 6 needs more attention because there is no BOF slag, the iron content is low and SR (SiO 2 …”

SLAG; VALUE ADDED STEEL INDUSTRY BYPRODUCTS ŻUŻEL; WARTOŚĆ DODANA ODPADU Z PRZEMYSŁU STALOWEGOSlag is a non metallic co-product, produced in the iron (BF) and steelmaking (BOF and EAF) process. Slag has been commonly utilized on a broad scale ever since these processes were first taken into use. Besides economical benefits, environmental requirements will enhance the need for further product development work concerning the properties of slag in the future, in order to observe the principle of sustainable development. Today, one of the important indicators of sustainable steel industry is quantity of slag (production) and its utilization. This paper discuss the utilization of slag in different fields such as cement, heat and sound isolation, filtration, agriculture, tile and glass production and explain some of important researches in last 35 years which done in Esfahan Steel Co. (ESCo) of Iran.

“…The calcium content (weight percent of total Ca) in steel slag ranged between 21 to 40%. [29][30][31] Therefore, the MCRP of the steel slag may be considered to be less than the above range. Thus, this proposed method can be applied to determine the MCRP for almost all slag types.…”

Sea grass beds and tidal flats are facing imminent dangers of extinction. Steel slags are one of the promising alternative materials for marine sands to restore sea grass beds and tidal flats. On the other hand, significant pH increase and solidification attributed to dissolving calcium released from the slags are sometimes negative impact on ecosystems. To quantify the dissolved calcium, Japan Cement Association Standard method is conventionally used. However, our study leveled the method underestimate the dissolved calcium from the steel slags. The purpose of this study is to optimize the determination method for maximum calcium releasing potential from steel slags. Powdered sample (0.1 g) was stirred in 40 mL of 99.5% ethyleneglycol-100 mM tris buffer solution for 6 h at 80±5°C. Thereafter, the solution filter through 0.45 μm filter and the dissolved calcium was determined by ICP-AES. The optimized condition proposed in this study recovered the dissolved calcium from the slag in seawater perfectly.

“…However, recycling of SS could be convenient provided that the produced materials possess good durability and maintain properties in line with the requirements of standards after long time aging. In this view, several authors proposed the use of blended cements containing SS for concrete manufacturing [11][12][13]. For this specific application, SS needs to be converted by milling into a powdered product.…”

Production and Compression Strength of Mortars Containing Unprocessed Waste Powdered Steel Slag

This paper deals with the production of mortars prepared using a commercial CEMIIB-S 42.5N cement, a natural aggregate, steelmaking slag, a superplasticizer and water. The as-received unprocessed steel slag was milled by a hammer mill and then sieved to obtain batches with different maximum particle size. Each batch was used, together with the other components, in the production of mortars which were tested, by compression and water absorption, after different aging times in order to evaluate their long term stability. Several slag-free samples were also prepared as reference materials. All mortars were prepared with fixed aggregate/cement ratio (6/1), superplasticizer/cement ratio (s/c) and water/cement ratio (w/c). It has been demonstrated that an adequate protocol for the preparation and the use of slag containing particles with 2500 µm maximum size lead to the production of materials with mechanical properties suitable for civil engineering applications after aging for 28, 90 and 180 days. However, samples containing slag particles with size equal or greater than 1000 µm display a decay of mechanical properties after longer aging in water or after accelerated aging.
