This paper presents the strength and durability of cement mortars using 0100 ferronickel slag FNS as replacement of natural sand and 30 fly ash or ground granulated blast furnace slag GGBFS as cement replacement. The maximum mortar compressive strength was achieved with 50 sand replacement by FNS. Durability was evaluated by the changes in compressive strength and mass of

The application of ultrafine groundgranulated blastfurnace slag GGBFS in concrete becomes widely used for high performance and environmental sustainability. The form of ultrafine slag UFS used in concrete is powder for convenience of transport and store. Dryinggrindingdrying processes are needed before the application for wet emission.

Ground granulated blast furnace slag GGBS is a nonmetallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The sie of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 kg.

201949slag cement at higher temperatures was also used by studies in refs. 912. In ref. 13 the author worked on the use of pelletised blast furnace slag and its effects on the freeeandthaw durability characteristics and reported its good performance in concrete. Although partial replacement of cement by SCM reduced the cement consumption it

Since more than 100 years blast furnace slags are used as additive material or substitute material in cementitious systems like mortar and concrete. Due to their different syntheses the slag systems have binding properties which differ from conventional clinker. With the help of mechanical activation due to fine grinding the properties of blast furnace slags are shifted towards clinker systems.

20151218General Information Blast furnace slag is a byproduct of the steel industry produced by adding a limestone flux to the ironore to remove nonferrous contaminants. Granulated Blast Furnace Slag is obtained by rapid cooling or quenching of molten slag

Granulated Blast Furnace Slag US Steel The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates Iron Calcium Magnesium Aluminum and Titanium Silicates including Fine dry material should be removed by vacuuming or wet sweeping methods to prevent spreading of dust Avoid using compressed air Do not release into sewers or .

2011629The dry process in the case of blast furnace produces a cement grade granulate of equal quality to that produced by the wet process. Hence it has increased value due to reduced energy requirements in subsequent processing. So the dry blastfurnace slag granulation arrangement application can dissolve such problems the dry even sied

2020323Electric Arc Furnace Slag EAF or steel furnace slag Produced when scrap metal and fluxes are oxidied by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include

Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 1550 deg C temperature. Till seventies blast furnace BF slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.
