Jun 29, 2017· Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas,
In this area of research, it has been concluded that slag is suitable for use in concrete under normal enviromental conditions and has more fire resistance than the commonly used aggregate, but when combined with Portland cement, slag does not provide increased fire resistance to concrete.
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 hydro-technical structures.
Jan 20, 2016· Use of by-products from the steelmaking process can play an important role in achieving sustainable development. The available literature suggests that the use of iron and steel industry slags as mineral admixture or partial replacement of cement improves the microstructure of the concrete as well as its mechanical and durability characteristics.
Nov 09, 2020· Steel slag is a large amount of residual material produced in the process of steel manufacturing. With the requirements of sustainable development in China, the utilization of steel slag has become a hot issue. Through an in-depth study on steel slag, it is apparent that it has been widely used in various fields in recent years. The resource utilization of steel slag is not only conducive to
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.
Apr 11, 2019· Since 2018, Metallo is producing fumed slag, under the trademark Koranel®, for which it was awarded the “Global Slag Product of the Year” (during the 14th Global Slag Conference in Aachen). [1] The slag is currently mainly applied for sand blasting, but extensive R&D has been performed to use the slags in other applications, such as in cementitious binders and engineered products.
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature controlof the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace a
The use of waste materials in highway construction in the United States and applications of selected wa te material inCluding waste 39 percent The use of steel slag bottom ash and boiler slag also seems fairly attractive for highway HIGHWAY INDUSTRY Waste Material States Material is Used
Slag cement (Ground Granulated Blast Furnace Slag) and fly ash (Coal Combustion Product) are the most commonly used supplementary cementitious materials in construction today. While they are commonly used and similar in many ways, these materials produce different effects on concrete performance and this document will explore those differences.
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 hydro-technical
The use of steel slag as a natural aggregate replacement material has been widely used in road construction as it has high density and hardness properties [8]. Meanwhile, the use of Cathode Ray
The use of steelmaking slag in the construction industry was first advanced in the seminal papers of Shelburne, Motz, Geiseler, Koros et al. (Shelburne and Degroot 1998, Motz and Geiseler 2001

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 iron-making forges of that era were used in base construction. Applications were quite sporadic until the last century, when large quantities began to be used for a number of purposes. In relatively recent
Carlos Thomas, Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.
Apr 11, 2019· Since 2018, Metallo is producing fumed slag, under the trademark Koranel®, for which it was awarded the “Global Slag Product of the Year” (during the 14th Global Slag Conference in Aachen).

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of either cement or aggregates.
Apr 28, 2016· Use of blast-furnace slag's as • Sand and gravel for the construction of road beds, • Basic filler in asphalt–concrete mixtures for the construction of road and airport coatings, • Unroasted cement (binder) for reinforcing roadways and • Preparing slow-setting concrete. Use of Blast Furnace Slag in Road Construction 23.
Slag is a by-product from production of both iron and steel, and ground iron slag another 1.1 million tonnes were imported for use by the construction industry.get price Appropriate use of waste materials in Infrastructure projects Slag
Apr 14, 2020· This project includes the construction of a 25-floor high end luxury condominium building off Bayshore boulevard in Tampa Florida. Slag cement was used on this project in multiple mix designs, however, the most important usage was a 50% replacement rate in the mix used for columns which required 10,000 PSI.
