Calculating Model of FetO Activity in AlkaliContaining BF ...The FetO activity calculating model of alkalicontaining BF slag was built according to the coexistence theory of slag structure at 1773K. The results reveal: it is correspond to reality and embody the structural characteristics of BF slag. The FetO activity of slag increases obviously with the w(CaO)/w(SiO2) increasing, decreases with the Al2O3 and MgO contents increasing.

Blast furnace Simple English Wikipedia, the free ...The slag is not waste. It can be used in various ways. It can be made into bricks and used for construction, or it can be mixed with concrete. Concrete which contains blast furnace slag is stronger than ordinary concrete and is almost pure white, where normal concrete is dirty grey. A blast furnace can usually work for 10 to 20 years without ...
Ohio EPA Policy Use of Blast Furnace and Steel Slag1. Use of steel slag and blast furnace slag in asphalt is encouraged from an environmental perspective. 2. Use of blast furnace slag in concrete is encouraged from an environmental perspective. 3. Generally, blast furnace slag does not represent significant environmental problems when used as a construction material above the ground water table.

Blast furnace slag granulation at cast house – IspatGuruMay 05, 2013· Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 – 1550 deg C temperature. Till seventies blast furnace (BF) slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.

Blast furnace Slag Research Papers This has brought in brutal strains on the accessibility of sand forcing the construction business to look for substitute building materials without compromising the strength criteria of concrete. Granulated blast furnace slag is one of the promising sustainable solutions as they are obtained as solid wastes generated while production of iron.
Steel manufacture It is also used in readymixed concrete, concrete products, asphaltic concrete, road bases and surfaces, fill, clinker raw material, railroad ballast, roofing, mineral wool (for use as insulation) and soil conditioner. Granulated slag forms sandsized particles of glass and is primarily used to make cementitious material.
EVALUATION OF CONCRETE PROPERTIES USING GROUND GRANULATED ...Abstract. Traditionally, Ordinary Portland Cement concrete is used for making the civil structures. Portland cement can be replaced by Ground Granulated Blast Furnace Slag (GGBFS) which is a nonmetallic and nonhazardous waste of the Iron industry.
(PDF) Characterization and Reuse Avenues of BOF Slag as ...Blast furnace granulated slag is a glassy aggregate and used as raw material for pozzolanic cement. But BOF granulated slag is crystalline and less glassy phase compared to BF slag, so 100 % utilization as pozzalanic cement manufacture is limited. Hence, alternate reuse avenues are under study at research or implementation level.

BF Slag | Glasses | Silicon DioxideBLAST FURNACE SLAG. Slag formation in Blast furnace. Slag is a fused product formed by the action of a flux (Limestone/Dolomite) upon gangue of ore or fuel or upon the oxidized impurities of metal. The BF slag is defined as the non metallic product essentially consisting of silicates and aluminoSilicates of lime and other bases which are developed simultaneously with iron in a BF.
