Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron The heart of the process is the blast furnace that refines iron ore into iron The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag
Abstract: A large amount of solid waste slag is generated in the production process in iron and steel enterpris As for enterprise which takes blast furnace as the process, blast furnace slag accounts for more than 50% Blast furnace slag disposal has experienced the following development: as a waste treatment, use in subgrade and foundation engineering, to the stage of comprehensive .
The bell-less system has the additional advantage that less energy rich blast furnace gas is lost during charging The additives and fluxes serve to convert the waste or gangue materials in the charge [mainly silica and alumina] into a low melting point slag which also dissolves the coke ash and removes sulphur
Supplementary cementitious materials such as blast-furnace slag (BFS) and pulverised-fuel ash have been used as a partial replacement for Portland cement (PC) in UK and international nuclear waste encapsulation for many years (Angus et al, 2010; Sharp et al, 2003)Encapsulation in a cementitious wasteform is the current preferred method of disposal of intermediate level waste in the UK .
long reducing conditions could persist in near-surface slag-bearing grouted systems for radioactive waste disposal The oxidant of most concern is oxygen (O2)—in the gas phase or dissolved in infiltrating water—which could react with the blast furnace slag and decrease the grout reductive capacity
