Blast Furnace Slag - an overview | ScienceDirect Topics

Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace. Usually, it is rapidly cooled to a glassy state and ground for use in construction materials (Provis et al., 2015).Influence of crushed granulated blast furnace slag and,,The objective of this research is to study the mechanical behavior of a compacted marl treated with a new hydraulic binder composed of Crushed Granulated Blast Furnace Slag (CGBS) active by Calcined Eggshell Waste (CES). To conduct this research, unconfined compressive strength tests (UCS), soaked California Bearing Ratio (CBR) tests, and triaxial shear tests are performed for different cure periods. The specimens were prepared with a binder(PDF) Influence of crushed granulated blast furnace slag,,composed of 90% crushed granulated blast furnace slag combined with 10% of calcined eggshell waste. The use only 5% of CGBS-CES binder after 56 days of curing time is able to increase 8.5 times

When cooled, the BFS is crushed and screened to a full range of aggregate sizes. There has been a significant amount of information published on the properties of BFS aggregates and further details on definitions are available in other technical literature1,2,3,

Blast Furnace Slag - an overview | ScienceDirect Topics

Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled. Depending on the cooling method the BFS can be produced as air-cooled, granulated, expanded and pelletizedPhysical Properties of Crushed Air-cooled Blast Furnace,,Crushed air-cooled blast furnace slag (SCR), a by-product of the iron industry, was obtained by crushing blast-furnace slag that solidified by slow cooling under atmospheric condition. SCR with 5-20 mm and 20-40 mm gradation were provided by Panzhihua Huanye Metallurgical Slag Exploiting Co., Ltd. Crushed limestone (LCR) is a coarse aggregate resulting from industrial crushing of limestone. 2,1.
