The order results from the Competition Commissions (CC) investigation into the supply or acquisition of aggregates, cement and readymix concrete in GB, which required Lafarge Tarmac to sell one of its cement plants and Hanson to sell one of its ground granulated blast furnace slag (GGBS) plants to enhance competition in the cement and GGBS ...
Recognized advantages. In addition, the density of electric arc furnace oxidizing slag aggregate under ovendry conditions is approximately g/cm 3, which is higher than other aggregates. This characteristic is put to use in applications such as radiation .
It also makes economic sense, as it is a cheaper material to use than clinker. The main application of FA is addition in cement and concrete production (about 2 Mt per year In the UK). There is a European standard for FA quality, of which the specifications are set in EN450.
Ground Granulated Blast Furnace Slag is used as a mineral admixture for Portland cement concrete. Usage: Slag cement is used in virtually all concrete applications such as: Structures and foundations, off shore and marine structures, mass concrete applications, such as dams, flyovers, bridges, precast components and
It was found that chilled blastfurnace slag introduced in moderate quantity and finely ground with the cement clinker did not injure, but usually improved, the quality of the resulting cement. This mode of, manufacture is recognized, especially in Germany, as a legitimate branch of the cement making industry.
The use of aircooled blast furnace slag in the production of concrete can have economical motivations—acquiring ACBFS, as a waste that is industrially generated, is cheaper than obtaining natural aggregates from a quarry. Additionally, the reuse of aircooled blast furnace slag has

rice husk ashes and ground granulated blast furnace slag (GGBS). Apart from improvement of the properties of concrete in fresh and hardened form, the use of SCM has also reduced the consumption of cement in concrete, thereby reducing the emissions of CO 2 in the atmosphere during manufacturing of cement. The extensive emissions

From this study it is observed that Blast furnace slag can be used as an alternative to natural sand up to 60% and 75% in mortar and concrete respectively. KEYWORDS: Concrete, Natural sand, Blast furnace slag, compressive strength.
improvement by the use of ground granulated blast furnace slag as a replacement of sand in concrete mixtures. The optimum percentage is between 30 % and 40 %, after those percentages there is no observed increase. Keywords: Concrete; Compressive strength; Flexural properties; Ground granulated blast furnace slag, replacement as a sand
slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environmental benefit to whole society.[9] 6. Ground granulated blast furnace slag is commonly used in combination with Portland cement in concrete for many applications[10,11] 7. The heat of hydration is dependent on the Portland
The BlastFurnace slag is a byproduct of the iron manufacturing industry. Iron ore, coke and limestone are fed into the furnace and the resulting molten slag floats above the molten iron at a temperature of about 1500 0C to 1600 0C.
PSC or Portland Slag cement is manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland cement by means of mechanical blenders.
Ground Granulated Blast Furnace Slag which is a byproduct of steel manufacturing industry is an accepted mineral admixture for use in concrete. This granulated material when further ground to less than 45micron is called Ground Granulated Blast Furnace Slag (GGBFS).
Two major uses of GGBS [2] are in the production of qualityimproved slag cement, namely Portland Blast furnace cement (PBFC) and highslag blastfurnace cement (HSBFC), with GGBS content ranging typically from 30 to 70% and in the production of readymixed or sitebatched durable concrete.
Structural concrete is designated by "Class" and pavement concrete by "Type." Portland cement concrete shall conform to the requirements of Table 901 3, "Master Proportion Table for Portland Cement Concrete." Fly ash or ground granulated blastfurnace slag (GGBFS) is permitted as a partial
