This report presents available information regarding the use of aircooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. The report discusses ACBFS aggregate production and properties, and the properties of concrete produced with ACBFS coarse aggregate. Both .
The characteristics of bricks made from steel slag were investigated in this research. Slag addition was shown to reduce the required firing temperature. When the firing temperature was greater than 1050 °C and the slag addition less than 10%, the bricks met ROC national standard CNS 3319 thirdclass brick .
CBD215. Waste and ByProducts as Concrete Aggregates. ... Aircooled slag is suitable as an aggregate in concrete. A comparison of the compressive strengths of concrete made with blastfurnace slag aggregate, and that with gravel and crushed limestone shows that slag concrete is stronger. ... Crushed, wellburnt brick makes a suitable ...
This document contains recommendations for best practices related to the use of aircooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. It is primarily based on the results of a review of available literature regarding the production and use of ACBFS as coarse aggregate in concrete pavements,
What is ''slag'' • ''Slag'' is a by product of either iron or steel making processes. • Blast Furnace Slag – Produced as a by product from iron making. Typically air cooled, then crushed and graded. • Steel Slag – Produced from steel making processes such as electric arc furnace, basic oxygen furnace, etc. Steel Slag Blast Furnace Slag
Using Recycled Industrial Materials in Buildings Greening the built environment. This information sheet discusses the use of recycled industrial materials in buildings as an alternative to materials and building products. Industrial materials are the ... Aircooled blast furnace slag can be used to
What is the abbreviation for AirCooled Blast Furnace Slag? What does ACBFS stand for? ACBFS abbreviation stands for AirCooled Blast Furnace Slag.
Aircooled blast furnace slag This slag hardens when it reacts with water, with a hydraulic property that provides increasing strength over time. Because of its large loadbearing capacity, it is used in road base course material in the same way as gravel. There is no risk of alkaliaggregate reaction, and this slag contains no clay or organic ...
use them. To date steel slag use on construction projects has not represented significant environmental problems. SCOPE: This interim policy addresses beneficial use of blast furnace and steel slag generated during iron and steel making. It has been developed with input from the Ohio Steel Industry Advisory Committee.
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
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.
Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is processed through a screening and crushing plant for use principally as a construction aggregate. Air cooled slag is not cementitious.
Nov 14, 2018· Usage in other construction materials – Steelmaking slag can be used in preparing glass ceramics. It is a potential material for ceramic production. Also, a suitable addition of steelmaking slag can reduce the firing temperature needed for clay bricks. Steelmaking slag can also be used to produce coloured paving bricks and tiles.
air cooled blast furnace crushing grinding. Blast Furnace Slag . Pelletized blast furnace slag, in contrast to aircooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g. ...
Broken bricks are mainly used for the construction of temporary buildings. slag. Aircooled slag is lump ore getting from blast furnace on cooling. Fly ash. You know that fly ash is one the main mineral admixtures used in concrete. Sintered fly ash is a lightweight material which can be used as an equivalent of stone ...
The largestvolume of recycled material used as construction aggregate is blast furnace and steel furnace slag. Blast furnace slag is either aircooled (slow cooling in the open) or granulated (formed by quenching molten slag in water to form sandsized glasslike particles).
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 using a laboratory mixer at a room temperature of 20°C. Here, the unit
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.
Air cooled blast furnace slag fine aggregate Granulated blast furnace slag fine aggregate Steel furnace slag, both fine and coarse Gravel Coarse Aggregates There is a specific requirement for gravel coarse aggregates regarding crushed particles. .
In this thesis the soil are stabilised by ground granulated blast furnace slag (GGBS) and this material is obtained from the blast furnace of cement plant, which is the byproduct of iron (from ACC plant, sindri). It is generally obtained in three shaped one is air cooled, ed shaped and another is in granulated shaped. The use of by
hydrogen sulfide gas,and have a greenishyellow color. Whe n exposed to air, the rate of leaching will diminish with time as the ACBF slag ages. The aging process will allow the calcium sulfide to oxidize to sulfates and carbonates. This procedure will apply to all uses of ACBF slag except for use .
Nov 25, 2018· Aircooled slag uses are many and varied, including all types of construction aggregate applications in addition to manufacture of mineral wool, cement and glass and as a soil conditioner. The principal uses of air cooled slag include road bases, asphalt concrete aggregate, concrete aggregate, structural fill, railroad ballast, and mineral wool.
Resources are depleting day by day due to non consumptive use by the mankind. Blast furnace slag has a great potential as it can be used as an artificial aggregate. Keeping this in view, the present study the present study encourages the utilization of waste material such as air cooled blast furnace slag (ACBFS) and fly ash in concrete.
