Cementitious Applications of Ground Granulated Blast Furnace Slag MF 1845 NATIONAL SLAG ASSOCIATION Page 4 10. Lighter color. 11. Lower cost. HISTORY OF USE Use of separatelyground slag combined with portland cement at the mixer began in South Africa more than 30 years ago. Watergranulated slags are used in 5050
Granulated blast furnace slag is made by rapidly cooling a slag melt of suitable composition. As described by Tsohos amp; Oppliger in [38], blast furnace slag contains 95 % or more oxides (silica alumina, lime and magnesia). It is classified in grades 120 100 80, based on the slag activity index (SAI).
Blast furnace slag is produced when iron ore is reduced by coke at about 1350#176;C 1550 #176;C in a blast furnace. The molten iron, main product of a blast furnace, is formed from the ore, while the other components form a liquid slag. When flowing to the bottom of the furnace, the liquid slag
GGBS (Ground Granulated Blast Furnace Slag) The Worlds Most Sustainable Building Material to Produce Strong and More Durable Low Carbon Concrete GGBS is Obtain By Quenching Molten Iron Slag (a By Product of Iron amp; Steel Making) from a Blast Furnace in Water or Steam, to Produce a Glassy, Granular Product that is Then Dried amp; Ground Into fine Powder.
Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. Titanium dioxide pigment can also be produced from higher titanium content feedstocks such as upgraded slag, rutile, and leucoxene via a chloride acid process. Most ilmenite ore production from Canada, South Africa and Norway is destined for
According to [6], a combination of lime and granulated blast furnace slag is commonly used in South Africa and Australia for soil stabilization. The sulphate in the soil is known to be able to cause serious swelling in stabilized clay. This sulphaterelated swelling is associated with the formation of ettringite.

One potential solution to this problem is geopolymerisation of industrial waste such as; Fly ash, mine tailings, foundry sand, basic oxygen furnace slag and granulated furnace slag as alternatives to OPC and clay resources,,,,,, . Less than 6% of GBFS is used as supplementary cementitious material in South Africa .
hand alkaliactivated slag cements using granulated blastfurnace slags were invented by Glukhovsky (1980) and patented in 1958. Alkali activated slags have been employed on a limited scale as oil well cements and as a roof support system in mine applications in South Africa and Canada. Industrial experience of precast products utilizing these

May 09, 2018#0183;#32;Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine
Top Blast Furnace Slag suppliers in world are South Africa (35%), Japan (13%) and India (%). Some of top companies that supply Blast Furnace Slag are AfriSam (South Africa), JFE Steel Corporation (Japan) and Tatametaliks (India). Blast Furnace Slag is gained as a derivative in the removal of iron from its ore. The procedure of removal of iron is the blast furnace.
Granulated Blast Furnace Slag : Granulated blast furnace slag or gbfs is the residue of combustion in the furnace of the steel refining process. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a
Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a byproduct of the ironmaking industry. For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of
granulated slag specifications were based on that of ground granulated blast furnace slag (GGBFS) specifications (EN197)8 which is widely used in the cement industry. Table 2 contains the GGBFS target specifications and the corresponding modified slag results. A mineralogical analysis was conducted to determine the presence of

Moreover, ground granulated blast furnace slag is a waste material from the metallurgical industry. A mixture of limestone, iron ore, and coke enters the kiln under temperatures from 15,000 to 16,000#176;C; the resulting molten slag is suspended in molten iron. The slag contains 35 to 45% silicon dioxide (SiO 2) and about 45% calcium oxide. The slag chemical composition is almost the same as that of ordinary
