Key words river sand, iron slag, mix design, replacement of slag, compressive strength i.Introduction the history of the use of iron and steel slag dates back a long way.European slag association 2006 has reported about the earliest reports on the use of slag, where in it is mentioned that aristotle used slag as a medicament as early as.
Water absorption 2.3 stainless steel slag waste 93 the stainless steel slag waste used in this investigation was obtained from a producer of 94 ferritic stainless steel produced by a steel plant acerinox in algeciras, cdiz, spain.The 95 steel slag is produced during the direct reduction of iron in an electric arc furnace.96 two different samples were obtained in.
The percentage of copper slag used for replacement of river sand are 0, 25, 50 and 75 cement sand mortar joint thickness of 10 and 15 mm plaster ability of use of copper slag for partial replacement material for river sand use of copper slag as replacement material for river sand in cement concrete 0, 25, 50, 75 and 100.
Gradation steel slag can readily be processed to satisfy the aashto m 147 8 gradation requirements for granular aggregates.Specific gravity due to the relatively high specific gravity 3.6 of steel slag, steel slag aggregate can be expected to yield a higher density product compared with conventional mixes 2.
Process on enhancement of volume stability of steel slag.Zeghichi, 2006 7 experimented on substitution of sand by gbf crystallized slag.Tests carried out on cubes of concrete showed the effect of the substituting part of sand by granulated slag 30, 50 and the total substi- tution on the development of compressive strength.
Shrinkage of steel slag exposed to a dry environment was similar to limestone aggregate.5 objecttives the objective of this research was to find combined aggregate gradations, using steel slag aggregate, which will significantly reduce the amount of cement required by 10 to 15 without compromising concrete properties.
