Blast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability. Slag aggregates produced by Tarmac are supplied as CE marked products under the Factory production control process of ISO 9001:2008 for the production of products to BS EN 12342 Aggregates for Unbound and Hydraulically Bound
Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a value-added product for the cement industry, using granulated slag sand as a CO 2-friendly substitute for clinker in cement production. Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA ® dewatering drum. With
27/10/2011· The density is higher than that of blast furnace slag or many commonly used natural rocks, and this can influence marketing; for some applications, such as use in waterways, the density is an asset. The high total lime content, often over 40%, and the fact that much of this lime content is held by minerals that are reactive under soil conditions, allows some slags to
14/2/2018· Possible Process Flowsheet. A series of tests were performed to demonstrate a possible flowsheet to recover zinc in solution, and directly reduced lead, from lead blast furnace slags. Initially a large scale sulfuric acid leach
20/10/2015· The use of cement replacements provides opportunities for significant reductions in energy use and carbon dioxide emissions. Ground granulated blast-furnace slag (GGBS), manufactured from a by-product of the iron-making industry, is one of the most common, and most sustainable, substitutes. The cementitious properties of blast-furnace slag were
Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process. In the primary process, crude steel is produced in two ways.
The Blast Furnace is a vertical shaft of circular cross-section and stands approximately 40 m high (although the overall facility approaches 100 m). The vessel is internally lined with cooling elements and refractory bricks and blocks. Iron ore, coke and fluxes are charged into the furnace to produce molten iron and slag. The Blast Furnace operates continuously with molten iron
