En ajoutant au laitier d'acier du minerai de fer en tant qu'agrégat, le revêtement de lestage en béton lourd économique peut avoir une densité supérieure à un revêtement ayant uniquement du laitier. Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. II. Cement was partially replaced with glass powder at varying percentages such as 10%, 20% and 30% and several concrete cylinders were casted along with plain concrete specimen. Published under licence by IOP Publishing Ltd DTA, EDX, XRD and ethylene glycol methods were employed to … The usage of this waste product will reduce the cost of concrete by partly substituting the coarse and fine aggregates. This study evaluates the use of Steel Slag Aggregates (SSA) as substitute for natural aggregates in the production of hot mix asphalt (HMA) for road construction. Thiruvalluvar govt.arts college Rasipuram. Concrete based on steel slag with CEM I 42.5N and H-CEMENT can be included in leachability class IIb. Also noted was a difference in deicer scaling resistance apparently The concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. aggregate ratio mixing method were examined. Iron and steel slag products: Concrete aggregate. Shaopeng W.,Yongjie X.,Qunshan Y.,Building and environment 2007.,vol 42 (7) pp 2580-2585. ) 6. The optimal percentage substitution natural sand by steel slag sand reached of slag on the percentage of 20 % which reached strength ratios of steel slag concrete to the strength of conventional concrete with natural sandstone were 1.37 for compressive strength and 1.13 for flexural strength. All specimens were denuded 24 hours after casting, an, The experiment was conducted to find the di, tensile strength; when the steel slag is replaced with fine aggregat, 14th and 28th days. 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. Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence. Mechanical properties of the concrete containing the steel slag and steel sludge were also evaluated. Mineral phases of SS are determined and … While the tensile strength reached a higher ratio of concrete with steel slag sand to the concrete with natural sand on the 80% substitution of natural sand with steel slag sand. Water engineer Dr Biplob Pramanik said the study was the first to investigate potential applications for "sewage-enhanced" slag in construction material. The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. If the unit cost of steel slag modified mixes is the same as conventional dense graded mixes, overall project costs may increase because of the decrease in coverage by the heavier steel slag mix. It is actually a byproduct of iron production. IOP Conference Series Materials Science and Engineering. compressive strength and split tensile strength at the age of 7, 14 and 28 days and were compared with the results of plain concrete. For this purpose, 12 different concrete mixtures with different water/cement ratios of 0.40, 0.55 and 0.70 which include steel slag aggregate as fine and/or coarse aggregate are prepared. Furthermore, the properties of concrete mix containing 100% RCA and 15% metakaolin are similar to that of normal concrete. In India between 7.7 and 8.3 million tons of steel slag are expected to be produced per year. Steel slag is a byproduct of the steelmaking process which is produced during the separation of the molten steel from impurities in the steelmaking furnace, and it is used as coarse aggregate in concrete. IS: 383-1970, " Specification for coarse and fine aggregates from natural sources for Concrete. The influences of steel slag on the compatibility of cement-superplasicizer system and workability of concrete were investigated in this study. 6. Despite its volume changes over time, steel slag can be applied in concrete as a cement replacement (normally) or as a substitute for natural aggregates (rarely). The needs for alternative sources of aggregates are pressing. In this research, laboratory investigations of the use of steel slag as a portland cement concrete (PCC) aggregate were reviewed. Admixtures like Metakaolin (MK) and Waste Glass Powder (GP) were used to replace OPC, producing, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. The physical and chemical properties of slag aggregate evidenced the feasibility of using this material as a substitute for river sand. Utilizing steel slag in concrete mixes has proved to be useful in solving some of the problems encountered in the concrete industry. Ground iron and steel slag with excellent performance was prepared using the uniform test design. The influence of the fineness and content of steel slag powder on the fluidity and strength of the powder mortar was studied, the regression equations of fluidity and compression strength of different ages are derived, and the contour map is drawn. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating can have a higher density than a coating having just slag. Purchase Characteristics and Uses of Steel Slag in Building Construction - 1st Edition. Comparisons of Compressive strength in Concrete 4.3. This study presents the results of an experimental evaluation of the performance of high strength concrete (HSC) with basic oxygen steel-making (BOS) slag and nano-silica respectively used as a partial replacement of sand and cement. The test results confirm the possibility to use steel slag as the filler in the production of concrete. Slag is by-product of steel making. However, the use of metakaolin in RAC significantly reduces the water absorption and volume of voids. In other sectors, such as thermal power plants or cement kilns and stainless-steel ovens, most waste tyre rubbers are used as heat. It also minimizes any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal. This study was motivated by the need for the development of eco-friendly concrete, and the use of large quantities of steel slag as an industrial waste which is generated from the steel manufacturers. 100% RCA and 15% metakaolin without much affecting the strength criteria. Export citation and abstract Murthi P.,Sivakumar V Indian concrete journal 2008 vol 82(7) pp 35. International Journal of Engineering & Technology. Mechanical properties are evaluated by conducting compressive, split tensile strength tests. The new system promotes stable microstructural phases' formation , able to retain metallic ions leaching, maintaining the same mechanical properties of the as-cast slag. RIS. slag (GGBFS). Eco-friendly and mass use of waste materials in construction is possible with the use of steel slag for partial substitution of concrete. Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. For example, at 50% BOS content, about 18% increase in compressive strength and 50% reduction in water absorption was observed, while slump was reduced by 40%. Steel slag is currently utilized both to treat wastewater, and as a concrete aggregate. Steel slags are by-products in the steel production industry and can be used for different purposes; e.g. The cement replacement with GP is from 5% to 45% and MK is from 45% to 5% both in steps of 5% and hence a total of ten combinations including control mixture (100% cement) were studied for M30 grade. The normal strength concrete with w/c ratio (w/c = 0.55) was used for this experimental investigation. Our slag cement CEMSlag TM is a hydraulic cement material created when granulated blast-furnace slag from the steel manufacturing process is ground to a fineness suited for concrete production. Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete. Much of this research took place outside the United States. Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements.
