The equipment and systems of modern Blast Furnace Technology are designed for the harsh .
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.
Steel Slag BOF slag commonly known as steel slag is another waste from Iron amp; S teel Industry. It has shown potential for use as a raw mix component up to 10 in the manufacture of cement clinker. Steel slag can also replace granulated blast furnace slag up to 10 in the manufacture of Portland Slag Cement. Steel slags are produced at steel .

Feb 24 2017 Blast furnace slag is a byproduct of the iron and steel industry. These slags mainly consist of Ca Mg Mn and aluminum silicates in several combinations. Typically about 300 to 540 kg of slag is produced per tonne of crude iron. Granulated blast furnace slag GBFS is produced by quenching the molten slag with high-pressure water jets.
Over the past 20 years the steel industrys recovery rate of co-products has increased significantly.

Nov 09 2017 The iron and steel slag used as aggregates for asphalt roads are iron and steel by-products. Steel slag is residue from the steelmaking process made of minerals like silica alumina and titanium from iron sand and combinations of calcium and magnesium oxides. During the steelmaking process slags float on top of the molten iron forming a .
Blast-furnace slag a by-product of the steel production obtains latent-hydraulic properties after rapid cooling and can thus replace clinker in cement. In EN 197-1 2000 three types of slag cements are defined CEM IIIA 36 - 65 BFS CEM IIIB 66 - 80 BFS and CEM IIIC 81 - 95 BFS.
