The primary applications for steel slag in the United States are its use as a granular base or as an aggregate material in construction applications. Disposal. While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal.
steel slag is mainly used as road aggregates; however the problems related to its volumetric instability and lack of studies that explore the engineering properties of steel slag have impeded the utilization of steel slag in other applications in construction industry, specifically for the finer fraction (sand and siltsizes ) of steel slag.
Green slag valorisation has been transformed from an academic concept into an industrial success story. In this article we review a number of these success stories and discuss the merits of legislation and green public procurement in view of stimulating the use of secondary (slag) .
Jan 13, 2017· The materials can then be reused in other projects. Naturally, this requires a quality assurance that recycled materials are safe for reuse in construction. Recyclers of construction and demolition waste can actually seek accreditation to prove the quality of their materials.
Blast furnace slag is a byproduct from blast furnaces which is used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation and energy savings.
A need was felt to identify potential alternative source of aggregate to fulfill the future growth aspiration of Indian construction industry. Use of slag as aggregates provides great opportunity to utilize this waste material as an alternative to normally available aggregates.
Steel slag is a byproduct of the steel industry and can be used potentially as aggregate in asphalt mixture. This study evaluates the use of Steel Slag Aggregates (SSA) as substitute for natural aggregates in the production of hot mix asphalt (HMA) for road construction.

Sand provides bulk, strength, and other properties to construction materials like asphalt and concrete. It is also used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a moulding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper.
Blends containing up to 70% slag cement are used for general construction. 2. Type IP (X), PortlandPozzolan Cement. Used for general construction, this blend can contain up to 50% pozzolan. Fly ash is the most common pozzolan used in blended cement. 3. Type IL (X), PortlandLimestone Cement.
Coal slag – abrasive blasting. According to OSHA, coal slag abrasive blasting (using coal slag as the blasting agent) is the most common exposure to beryllium in construction. For many applications, coal slag has replaced sand as the blasting agent because of .
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. Blast furnace slag products have been used successfully in virtually all phases of bridge construction.
Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or a...
The ready mixed concrete industry consumes about 75% of the cement shipped in the Besides portland and blended cement it uses a large quantity of industrial byproduct material that would otherwise be considered waste products. These include fly ash from the coal burning power plants, slag from the manufacture of iron and silica fume from ...
Crushed stone is one of the most accessible natural resources, and is a major basic raw material used by construction, agriculture, and other industries. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic wellbeing of a nation.
Sulfate resisting cement is used in construction exposed to severe sulphate action by water and soil in places like canals linings, culverts, retaining walls, siphons etc. 7. Blast Furnace Slag Cement. Blast furnace slag cement is obtained by grinding the clinkers with about 60% slag and resembles more or less in properties of Portland cement.
Slag utilization in highway construction is an overall process which includes several stages from slag production to end uses. Successful utilization is generally based on several stages or links. The overall general process consists of seven links, as shown in Figure 1, any one of which might affect the final use of the specific slag in highway
Jan 25, 2018· Figure 1. Slag aggregate was used to build the Roman Appian Way over 2000 years ago. Source: National Slag Association Every day you probably use a steel industry byproduct, slag, without realizing it. Slag is a common construction material in the building of roadways, bridges and buildings.
Characteristics and Uses of Steel Slag in Building Construction. focuses predominantly on the utilization of ferrous slag (blast furnace and steel slag) in building construction.. This extensive literature review discusses the worldwide utilization of ferrous slag and applications in all sectors of civil engineering, including structural engineering, road construction, and hydrotechnical ...
Steel furnace slag typically forms a very angular, durable aggregate that makes it ideal for use in the transportation industry. SFS has been used successfully in the friction course of hot mix asphalt pavements, as well as in Superpave mix designs and stone matrix asphalt.
Slagment is the registered trade name of our Ground Granulated Blast Furnace Slag (GGBFS). It is a latent hydraulic binder that is used in concrete and other construction applications as a partial cement replacement material. We have the capacity to produce over 800 000 tons of slag per year at our Slagment operation in Vanderbijlpark.
The history of slag use in road building dates back to the time of the Roman Empire, some 2000 years ago, when broken slag from the crude ironmaking forges of that era were used in base construction. Roads made from Slag were first built in England in 1813 and, just seventeen years later, the first Slag road was laid in this country.
Steel slag is a byproduct obtained from steel industry. It is generated as a residue during the production of steel. Because of the high disposal cost as a waste material and the overall positive ...
