Steelmaking slag consists of converter slag that is generated by converter and electric arc furnace slag that is generated during the electric arc furnace steelmaking process that uses steel-scrap as the raw material. Converter slag In the same way as air-cooled blast furnace slag, converter slag is cooled slowly by natural cooling and water ...
The main contributors to global CO 2 emissions from industrial sectors are the steelmaking and cement industries. Both steelmaking via electric ... of steelmaking slag ... India; Nature Japan ...
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement).
Basic Oxygen Furnace (BOF) slag is a major waste product generated during the steelmaking process. In India and in most industrial countries, the use of BOF slag as a road ballast and land filler has had a very long history. This being a low end use, a study was conducted to examine the possibility of converting the slag into a hydraulic binder.
Association, replacing Portland cement with slag cement in concrete can save up to 59% of the embodied CO 2 emissions and 42% of the embodied energy required to manufacture concrete and its constituent materials. However, this does not ... 80% for steelmaking slag to nearly for ironmaking slag.
Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient , Ancient China, India, and Rome but the process of ancient steelmaking was lost in the West after the fall of the Western Roman Empire in the 5th century CE.
Jan 20, 2016· Abstract. Use of by-products from the steelmaking process can play an important role in achieving sustainable development. 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.
Mar 16, 2019· The iron and industry produces very massive amounts of slag as by-product of the iron creating and steelmaking processes. As helpful recycled materials, iron and steel creating slag ar mainly utilized in fields associated with civil engineering, as an example, in cement.
The new unit will process 2.4Mt/yr of slag, replacing an obsolete unit, which processed 1.7Mt/yr of slag. Metal extraction efficiency at the new unit will be as high as 95%, which will minimise the consumption of iron ore and scrap in pig iron and steelmaking operations through replacement with recoverables. The project had an investment of US ...

SLAG - IRON AND STEEL THM : Tonne Hot Metal Blast Furnace Slag In the blast furnace, the slag floating over molten pig iron (hot metal) is flushed out in slag pot and then sent to slag granulating plant or to cooling pits. Depending upon the cooling process, three types of slags are generated, namely, air-cooled slag, granulated slag and ...
, such as ordinary Portland cement (OPC). Granulated BF slag is highly active chemically; it is characterized by a strong latent hy-draulic property, i.e., the tendency to form hydrate compounds and harden when in contact with alkali solution, and for this reason, is used as the raw material for BF slag cement. Steelmaking slag and
Slag cement, a byproduct of steel-making, enhances the traditional concrete benefits of strength and durability while offering reductions in waste, energy use and greenhouse gas emissions. Slag cement is used in concrete for virtually any construction application, either in conjunction with traditional portland cement, part of blended cement or ...

PDF | Current total productions of steel slag in India, are around 12 million tonnes per annum (Indian Minerals Yearbook, May 2016), which is far behind the developed countries. Presently in India ...
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
AASHTO M240 describes three types of blended cements containing slag. (3) They include Portland blast furnace slag cement (type IS), slag modified Portland cement (type I (SM)), and slag cement (type S). The primary distinction among the three types is the percentage of slag they contain.

12.22 million tons of steelmaking slag. As useful recycled materials, iron and steelmaking slag are mainly used in fi elds related to civil engineer-ing, for example, in cement, roadbed material, and concrete aggregate. Their recycling ratio is close to , making an important contribution to the creation of a recycling-oriented society.
Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased ...

treated slag under different percentage ratios of slag and cement. Materials and methods Steelmaking slag was collected from the slag dumping yard in Jamshedpur, Jharkhand, India. Slag was screened for different particle sizes, washed with distilled water and dried at 150°C for 24 h and then kept in a desiccator until further use.
Bharathi Portland Slag cement is manufactured by inter grinding high quality clinker with carefully selected, good quality slag purchased from major steel plants and using high quality gypsum. This alkali is a byproduct in any OPC hydration process amounting to 25% of total gel formation. This is .
