Ground granulated blast furnace slag (GGBS) has been used in composite cements and as a cementitious component of concrete for many years. The first industrial commercial use (about 1859) was the production of bricks using unground granulated blast furnace slag (GBS).
How Plasma Converters Work. If slag is aircooled, it forms black, glassy rocks that look and feel like obsidian, which can be used in concrete or asphalt. Molten slag can be funneled into brick or paving stone molds and then air cool into readytouse construction material.
When it is ejected from a blast furnace, the slag is molten at a temperature of approximately 1,500℃. Depending on the cooling method used, it is classified either as aircooled slag or granulated slag. The molten slag flows into a cooling yard, where it is cooled slowly by natural cooling and by .

The granulated slag is used for cement manufacturing while the aircooled slag is used as aggregates in road making. This has been fully utilized throughout the world. It has been proved that more than 50% of clinker is replaced by additives like blast furnace granulated slag in the production of cement.
PDF | This study has been conducted to explore the possibility of utilization of steel slag in concrete as coarse aggregate. After collection of steel slag aggregate from a local steel ...
Aircooled slag can be used as a storage pad material for winter storage of animal feed or silage and for storage of cotton bales. Slag aggregates have been used for phosphorous and e. Coli removal from waste waters and research continues into what can be done with the used aggregates afterwards.
Land sand from the city of Kashima, Ibaraki, was used as the fine aggregate, and coarse aircooled BF slag from Kashima Works of the Company was used as the coarse aggregate. 3) Study of mixing ratio Concrete was trial mixed in different ratios shown in Table 4 us ing a laboratory mixer at a room temperature of 20°C.
Granulated blast furnace slag. Just like aircooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkaliaggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement.

Possible Uses of Steelmaking Slag in Agriculture: An Overview 337 Bessemer or Thomas processes, as phosphating and/or agent started in 1880 (Geiseler, 1996). Fig. 2. The scrapbased steelmaking. The traditional use of slag as landfill material, .
Therefore, about 80% of granulated slag is used as a raw material for cement The remaining about 20% of blast furnace slag is aircooled, produced by subjecting hot molten slag to air cooling and moderate water sprinkling Aircooled slag is similar in appearance and properties to crushed stone It is a substitute for natural crushed stone used ...
Slag: means air cooled iron blast furnace slag. CONSTRUCTION General Operational Constraints For those applications permitted in this special provision, it is the Contractor's responsibility to notify the District Manager of the local District Office of the Ministry of the Environment (MOE), of the locations where slag will be utilized.
quenching, the slag was cooled quickly by water after being held at 1 623 K. In air cooling, the crucible was placed on a refractory brick and cooled in air. In furnace cooling, slag was cooled to 1 323 K by a furnace at a cooling rate of 5 K/min. In this case, the slag was withdrawn from the
Aircooled Slag. Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in readymix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.
The company supplies and transports many raw materials such as: Aircooled slag: aircooled slag is a byproduct of smelting iron ore in high temperature furnaces. It is the gangue that is separated from the pure metal and discarded; it is allowed to slowly cool by ambient air. It has high content of calcium oxide, ferric oxide, and silicon ...
This molten iron product can be cast into iron products, but is most often used as a feedstock for steel production. Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calciumaluminasilicates.
et al. [33] demonstrated several scientific ways in producing geopolymer bricks form water cooled slag, and clay brick waste (grog) in a ratio ranging from 0 up to , and with a fine sand ratio of 15% of the total weight with 8 % sodium hydroxide activator. Results revealed the feasibility of substituting water cooled amorphous slag
