Basic Oxygen Furnace Slag Concrete

Applicability of Basic Oxygen Furnace Slag as a Concrete ...

Little basic oxygen slag is used as a portland cement concrete aggregate because of its unsoundness in concrete. However, soundness of basic oxygen furnace slag in concrete appears to largely depend upon the mineralogical and chemical compositions of the slag.

Recycling of Basic Oxygen Furnace Slag as a Raw Material ...

The purpose of this study was to recycle basic oxygen furnace (BOF) slag in the production of autoclaved aerated concrete (AAC), and to examine the influence on the properties of AAC products. The magnetic substances in the BOF slag accounted for about 15 wt.% and the magnetic proportion increased as the particle size decreased. The nonmagnetic portion of the BOF slag was acquired by a ...

Evaluation of Basic Oxygen Furnace (BOF) material into ...

2016-7-15  Basic Oxygen Furnace (BOF) slag has many prismatic angles, is massive, and has a high hardness that meets the requirements of the aggregate used in asphalt concrete. BOF has a higher proportion of CaO but a lower proportion of SiO 2 than natural (gravel) aggregate (NA) because CaO is a lipophilic molecule while SiO 2 is a hydrophilic molecule ...

High-gravity carbonation of basic oxygen furnace slag for ...

2016-6-15  1. Introduction. As the demand for steel and cement are increasing significantly around the world, great amounts of CO 2 and industrial wastes are generated during their manufacturing processes (Chen et al., 2014a, Hasanbeigi et al., 2012, Schneider et al., 2011).In addition to CO 2 emission, basic oxygen furnace slag (BOFS) is the by-product generated from the processing of iron to steel.

Characterization and activation of Basic Oxygen Furnace slag

2012-1-1  Highlights We propose a comprehensive methodology for Basic Oxygen Furnace slag characterization using complementary techniques. We study the chemical activation of BOF slag hydrated pastes with different chemical admixtures. BOF slag mainly contain C 2 S, C 2 F, Ca(OH) 2, Fe 1− x O, CaO, and with fewer proportions CaCO 3, SiO 2 and MgO. CaCl 2 significantly increases the

Utilization of Basic Oxygen Furnace (BOF) slag in the ...

2006-5-1  Basic Oxygen Furnace (BOF) slag is a major waste product generated during the steelmaking process. In India and in most industrial countries, the use of BOF slag as a road ballast and land filler has had a very long history. This being a low end use, a study was conducted to examine the possibility of converting the slag into a hydraulic binder.
