On the other hand, the increase of slags recovery and use in different fields of application, such as in agriculture, allowed to reduce landfill slags and to preserve natural resources. The consumption Most of the volume of concrete is aggregates. Disposal of different wastes produced from different Industries is a great problem for any country. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. It is found that under CO 2 rich environment, the steel slag is very carbonation reactive, and hence has a big potential to be used as the feedstock for CO 2 sequestration. Steel LD slag can also be used in fertilizers for agricultural applications (Das et al., 2007). The available literature suggests that the use of iron and steel industry slags as mineral admixture or partial replacement of cement improves the microstructure of the concrete as well as its mechanical and durability characteristics. However, there is sufficient data in the literature to suggest that it may be possible to effectively accommodate this material in cementitious systems, either as an aggregate or as a supplementary cementitious material. Evaluation of the use of steel slag in concrete. How to Garden With Basic Slag. Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. Silicate, lime, phosphate, and magnesia create healthy rice plants. A consecutive early rice-late rice rotation experiment was conducted to test the impacts of steel slag on soil pH, silicon availability, rice growth and metals-immobilization in paddy soil. Use of by-products from the steelmaking process can play an important role in achieving sustainable development. LD steel slag as fertilizer in agriculture. Possible Uses of Steelmaking Slag in Agriculture: An Overview Because concrete is a structurally sensitive material, one localized failure (one particle failure) will be regarded as failure of the concrete. Around 8%-12% of steel slag is mixed to attain the ideal properties of the binder material. The quantities of slag obtained world wide are increasing, … Environmental ris assessment of steel-ma ing slags and the potential use . Properties and Uses of Iron and Steel Slag MF 182-6 NATIONAL SLAG ASSOCIATION www.nationalslagassoc.org Page 5 Granulated blast-furnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. In Ukraine, we have been researching its value to farmers to improve soil properties and crop yield. Other uses include, glass making, trace elements in agriculture, concrete block manufacture, sporting field sub-base (for drainage), filtration medium, reinforced earth embankments, and mine backfilling and grit-blasting medium requiring fine etching. The materials are used to maximise yields of cultivated crops and pasture, improve soil texture and neutralize high soil acidity. Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. In agriculture, slag aggregates (Ag-Slag) have been used as an agricultural liming material since the 1920's in all types of crop production and landscaping. 3. A usability criterion for steel slag use in confined conditions can be developed by relating the allowable stress of a known matrix material and the maximum expansion force (stress) of a steel slag particle. Along with the diversified uses, steel slag efficiently replaces natural aggregates both coarse and fine, in a conventional concrete mixture. Concrete. In Ukraine, we have been researching its value to farmers to improve soil properties and crop yield. Fertile thinking: farmers benefiting from steel slag. Use of Steel Slag in Agriculture and for Reclamation of Acidic Lands Introduction This guide discusses the use of steel slag, a co-product of the steel making process, as a substitute for limestone for agricultural applications, and its use in reclamation of acidic lands. RESEARCH ON THE USE OF SLAG FROM THE STEEL INDUSTRY IN AGRICULTURE AND FOR AMELIORATION ACIDIC SOILS Valentina Mihaela, PETCU (VASILE)1, M. MIHALACHE² University of Agronomic Sciences and Veterinary Medicine of Bucharest, Faculty of Agriculture Corresponding author: mihaelapetcu2505@yahoo.com Abstract. Some of these include: reducing solid waste disposal costs incurred by industries, reducing landfill requirements, minimizing damage to natural resources caused by excavating earthen materials for construction, conserving production energy, and ultimately providing sustainable construction and economic growth. The increase of slag recovery and use in different fields of application, such as agriculture, is an imperative way for sustainable development . The percentage of metal slag in the mix was gradually increased and accordingly readings were noted down. To achieve this goal in concrete pavement, various substitutes were found to be replaced with natural aggregates of concrete. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resource-conservation and energy-saving effects. Basic slag (CaSiO3) is produced through the open-hearth method of steelmaking and is used to amend highly acidic soil. Introduction According to Nippon Slag Association’s statistics on the use of slag in 2012,1) the consumption of blast furnace slag was 1 390 000 tons for civil engineering, 18 220 000 tons for cement production, and 3 340 000 tons for sub-base course material. Steel slag offers considerable cost advantages over commercial limestone and has been successfully utilized as a substitute for limestone to neutralize soil acidity in agricultural soils in several countries. A wide variety of steel slag buyers options are available to you, such as stainless steel scrap. 6 Determination the mechanical characteristics of EAFS For the purpose of determining suitability of EAFS for usage in the production of asphalt mixtures, it was exposed to the testing of its geometric, physical and mechanical properties, as well as durability were. NIPPON STEEL & SUMITOMO METAL TECHNICAL REPORT No. Fertile thinking: farmers benefiting from steel slag. of LD slag in mitigating methane emissions an d the grain arsenic level in rice (Oryza sativa L.). 109 JULY 2015-130-1. Slag generated from basic oxygen furnace (BOF) or Linz-Donawitz (LD) converter is one of the recyclable wastes in integrated steel plants. As a major by-product of our industry, slag has long been sold by steelmakers for use in construction, but its use in agriculture has been less well known. In India, use of Steel Slag is very minimal. The efforts have been made in Tata steel that LD slag after grinding to 300 mesh, can be used as a soil conditioner in paddy field, tea gardens etc (Basu et al., 2002). The National Natural Science Foundation of China entitled “Immobilization of heavy metals in a contaminated paddy soil using nano-slag-based silicon fertilizer and ecological assessment” (Approved No. results showed a significant scope of use of steel slag, along with the bitumen as a binder. Owing to its high Si content, the use of slag as silicate fertilizer is gaining demand. The increasing demand for road construction led researchers to search for an economical and ecological pavement design. Slag consists mostly of mixed oxides of elements such as silicon , sulfur, phosphorus, and aluminum, and products formed in their reactions with furnace linings and fluxing substances such as limestone ( Yildirim and Prezzi, 2011 ; Piatak et al., 2015 ). This has attracted increasing attention from researchers and abundant work has been focused on this. The government is particularly interested in using slag in areas with acidic soils, mostly in the eastern part of the country where productivity is lower, according to the Financial Express newspaper. As a major by-product of our industry, slag has long been sold by steelmakers for use in construction, but its use in agriculture has been less well known. The most common process is quenching with water, but air or a combination of air and water may be used. 1,594 steel slag buyers products are offered for sale by suppliers on Alibaba.com, of which other metals & metal products accounts for 1%, steel scrap accounts for 1%. Effective in improving iron-poor soil (preventing root rot, leaf blight, and autumn paddy degradation). Iron oxides and manganese give vitality to roots. These materials pose environmental pollution in the nearby locality because many of them are nonbiodegradable. 3. Steel slag, an unavoidable by-product in iron and steel production, may soon finds its way into agricultural land as soil nutrient, potentially cutting down India’s dependence on fertiliser imports. India: The Ministry of Steel has asked that the Ministry of Agriculture examine using slag from steel and iron production as a fertilizer. Current production of steel slag is around 12 million tonnes per annum. Steel furnace slag is one such by-product material that has seen minimal use, owing to the potential for significant expansive properties. Converter lime fertilizer (using iron and steel slag) Application Advantage Example of use; Wet rice farming . Use of steel slag has several benefits to the State.
