Development of Environment-friendly Block Made of Steel Slag

Electric arc furnace slag and its use in hydraulic concrete

“…Other authors [74,76] have published works in which such values are fixed and are represented in graphs in terms of the distance to the aggregate particles. In our case, the fall in hardness can be appreciated in the zone close to the slag particle contour (hole) in which values are slightly under 200 MPa; from a distance of 5-20 microns the values are almost-constant, and homogeneous values of around 300 MPa are only measured in the matrix at a distance of over 25 microns.…”

“…At the start of the 21st century, their work and those of other Japanese authors [72][73][74] were published in English, and several new research teams begin to work on this subject. Our team began its research in this field in 1997, beginning with the PhD Thesis of Prof. Manso; an initiative now exists among several EU research groups to establish pre-normative standards in this field.…”

Freezing and Thawing Resistance of Steel-Making Slag Concrete

“…The density of ground granulated blast furnace slag was 2.89 g/cm 3 and the specific surface area by Blain was 4,000cm 2 /g. The density of fly ash was 2.20 g/cm 3 .…”

“…The aggregate used in this project of steel-making slag concrete was steel-making slag. Steel-making slag concrete is expected as a material reducing environment load 2) . After many demonstrations of construction with steel-making slag concrete were carried out, a technical manual for steel-making slag concrete was published 3) .…”

Fatigue characteristics of steel-making slag concrete under compression in submerged condition

“…Steel-making slag concrete [3], hereafter it is referred as SSC, is made of ground granulated blast-furnace slag, steel-making slag, pozzolan (e.g. coal fly ash), and alkaline activator (e.g.…”
