1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

As a valuable byproduct of iron-making process, blast furnace slag contains tremendous amount of sensible heat. Granulation of blast furnace slag is the first step for its heat recovery. Due to environmental and energy issues, dry centrifugal granulation has received a considerable amount of attention. However, the flight dynamics of blast furnace slag, which is of great importance for size des...

The blast-furnace process consists of a large number of processes that are physicochemical, thermal and mechanical interconnected processes. In addition to main processes consisting of iron oxides reduction, pig iron and slag melt creation, also realised are fuel combustion, gas flow, charge and melt flow, dissociation and other reactions in the solid and liquid phases. Inputs to the blast-furn...

air cooled blast furnace slag is a by product made of gradually air cooled molten blast furnace slag, and is often stored in stockpiles near the iron mills and usually occupy a wide area around the iron mills. from this perspective the further use of these materials can have its own merits. air cooled blast furnace slag can be used in asphalt mixtures because of their proper frictional properti...

Elementary and phase composition as well as micrography of the electric furnace slag were examined. The base of slag is made from phases containing Fe, Mn and Ca. Grains differ in size and shape, they cling together to form bigger or smaller agglomerates, depending on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase...

In developing country like India due to the remarkable development in road infrastructure, Soil stabilization has become the major issue in construction activity. Stabilization is an unavoidable for the purpose of highway and runway construction, stabilization denotes improvement in both strength and durability which are related to performance. Stabilization is a method of processing available ...

Slag fuming is a process of extracting zinc from molten slag in the form of metal vapor by injecting or adding a reducing source such as pulverized or lump coal, natural gas, etc. Top Submerged Lance (TSL) technology has been successfully applied to extract zinc by a fuming process from residues from the zinc industry, ISF and QSL slag and Lead blast furnace slag. A Computational Fluid Dynamic ...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...

A large amount of blast furnace slag is generated in China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications. Blast furnace slag, ground to an appropriate fineness, can be used as a partial replacement of cementitious material in concrete. The potential for using GGBS in structural concrete, e.g. concrete beams and columns is investigated at Xi’an Jiaot...
