Two major uses of GGBS [2] are in the production of quality-improved slag cement, namely Portland Blast furnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70% and in the production of ready-mixed or site-batched durable concrete.
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield ...
White Cement. White Portland Cement is made from raw materials containing very little iron oxide and manganese oxide. Burning in the kiln is done with furnace oil or gas instead of coal. Limited quantities of certain chemicals, which improve the whiteness of cement, are added during manufacturing. This type of cement is generally meant for non ...
SLAG - IRON AND STEEL CONSUMPTION The BF slag in India is used mainly in the cement manufacture and in other unorganised work, such as, landfills and railway ballast. A small quantity is also used by the glass industry for making slag wool fibres. Cement plants in the country producing slag cement require BF slag in granulated forms. The ...
NATIONAL SLAG ASSOCIATION Page 3 Blast-furnace slag uses in cements, where it maintains its separate identity and is a cementitious component, are divided by Lea6 into three categories: (a) Ground glassy (granulated) slag is mixed with hydrated lime. The slag cement
Mar 01, 2011· The Indian cement industry consumed 7.5 Mt of slag in 2008–2009 [6].Table 3.3.4 presents an overview of blast furnace slag produced across plants and the price at which it is being sold. Utilization of blast furnace slag in the cement industry has the same barriers or problems as fly ash.
Slag cement also produces a smoother, more defect free surface, due to the fineness of the Slag particles. Dirt does not adhere to Slag Cement concrete as easily as concrete made with Portland cement, reducing maintenance costs. Slag cement prevents the occurrence of efflorescence, the staining of concrete surfaces by calcium carbonate deposits.
Ground granulated blast furnace slag consists essentially silicates and aluminosilicates of calcium. Portland cement is a good catalyst for activation of slag be chained the three main chemical components that activate slag: lime, calcium sulfate, and alkalies.

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
SLAG - IRON AND STEEL 16 Slag - Iron and Steel S lag is a by-product generated during manufacturing of pig iron and steel. It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making .
Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. These operate at a temperature of about 1, 500 degrees centigrade and are fed with a carefully controlled mixture of iron-ore, coke and limestone.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used ...
