Applicability of Basic Oxygen Furnace Slag as a

01-05-1983  However, soundness of basic oxygen furnace slag in concrete appears to largely depend upon the mineralogical and chemical compositions of the slag. Several experiments concerning workability, compressive strength and dimensional stability of concrete made with basic oxygen furnace slag were conducted for investigating the possibility of the use of basic oxygen furnace slag as a

Evaluation of Basic Oxygen Furnace (BOF) material

15-07-2016  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, so BOF can be more closely integrated with

Basic oxygen furnace slag - Euroslag

Basic oxygen furnace slag – BOS (also called LD-converter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace. In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen.

Abstract: 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.
