From the test result, the weight loss of 40% replacement fine aggregate by steel slag is lesser when compared to the conventional concrete and 30% coarse aggregate replacement. By adding steel slag, either in fine aggregate or in coarse aggregate, has better acid resistance than our conventional concrete.
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
Oct 01, 2019· Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.
Blast Furnace Slag is the co-product of iron making in a blast furnace, while Steel Slag is a co-product of steel making in a BOF (Basic Oxygen Furnace) or EAF (Electric Arc Furnace). Blast furnace slag is used in a variety of applications including structural concrete, mineral wool, and glass manufacture.
Steel slag has been utilized worldwide in waterway construction. Applications include use of slag for erosion control, mineral filter applications, bank reinforcement, and construction of dikes, reefs and sea walls. Slag ballast for railroad applications is singled out for first preference over any other type of ballast.
Steel slag also reduces CO 2 emissions because it is calcined in the steel making process. It also saves valuable raw materials for another day and the CO 2 pt that would be emitted from the clinkering process. Another benefit to the cement manufacturer from using steel slag is iron oxide in steel slag needed in the chemistry of Portland cement.

Although it can be used as an artificial source of aggregates, it is sent to landfills for disposal. The disposal of steel slag occupies a significant portion of landfills and causes many serious environmental problems. This study aims to investigate the feasibility of utilizing steel slag aggregates in Stone Matrix Asphalt (SMA) mixtures.
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 .
Dec 16, 2004· I have used that company for slag from the steel mills. They have an office in South Bend, IN. When I bought it the price was about $300.00 for a 20 yard load. I had 5 loads delivered.

Screening of the steel slag will be done to ensure the aggregate is suitable for use as construction material. Since 1993, steel slag aggregates have been used commercially in the region for road surfacing . Steel slag contains significantly higher calcium oxide and iron oxide compared to granite rock.
The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment.
The shape and physical characteristics of iron and steel slag are similar to ordinary crushed stone and sand, however due to differences such as the chemical components and cooling processes, it is possible to provide different types of slag with a wide variety of unique properties.
Although blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate tends to be slightly alkaline and does not present a corrosion risk to steel in pilings (10) or to steel embedded in concrete made with blast furnace slag cement or aggregates.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world.
