Electric Arc Furnace Slag in Concrete Journal of
Nov 15, 2004 This paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace EAF slag as fine and coarse aggregate. To do this, the slag obtained in the steelmaking process must be crushed and stabilized. First, a suitable mortar must be made and tested.
Basics of slag production Article on the slag industry
Oct 27, 2011 In tonnage terms, blast furnace slag is at present the main type followed by slags from the Basic Oxygen Steelmaking BOS and Electric Arc Furnace EAF processes. Various other processes such as external desulphurisation of steel may generate significant amounts of slag at some plants but overall they are only a small proportion of the total.
Fly Ash Slag Silica Fume and Natural Pozzolans
ground granulated blast furnace slag and ACI 233 1995 provides an extensive review of slag. SILICA FUME Silica fume, also referred to as microsilica or condensed silica fume, is a byproduct material that is used as a poz-zolan Fig. 3-7. This byproduct is a result of the reduction of high-purity quartz with coal in an electric arc furnace in

Applicability of Carbonated Electric Arc Furnace Slag to
Authors have been studying the absorption of CO 2 in the steelmaking slag. In this study, an application of the electric arc furnace slag after the carbonation to admixture of mortar was investigated with the JIS A6206-1997 method for ground granulated blast-furnace slag for concrete. The percent flows for the test mortar were smaller than that for the standard mortar.
