It can be observed that the concrete where sand is replaced by copper slag, imperial smelting furnace slag, class F fly ash exhibits improved strength and durability properties, but it''s slump increases as the rate of replacement increases in the case of copper .
Jul 01, 2019· Therefore, the granulated lead slag can be used as a substitute for sand and natural aggregates in road construction. Li et al. (2016) selected the lead slag to replace part of sand as aggregate for road bases. When 15% of lead slag and 5% of cement are used, the compressive strength of road pavement can meet the requirements of ordinary ...
Ground granulated blast furnace slag (GGBS) GGBS is used in this study for the partial replacement of Portland cement. GGBS is the byproduct obtained during the manufacture of pigiron. When coke, iron ores, and lime stone are sent into the furnace, the molten slag is obtained at the top layer of molten iron at a
materials to replace river sand. Granulated Blast furnace Slag (GBFS) a waste industrial by product is one such material identified for replacement of natural sand. This paper highlights upon the comparative study for the utilization of GBFS as replacement of natural fine aggregate in

According to the precursor studies, furnace slag, as a partial replacement for cement, can increase the compressive strength and durability of concrete (Razak andSajedi 2011, Shariati et al. 2020c
Pyrometallurgical Process. Pyrometallurgical processes have been used to retrieve PMs over the past 2 decades, as well as for removal and recovery of heavy metals. This procedure involves the incineration of wastes, followed by smelting in a blast furnace, drossing, melting, sintering, and reactions in gaseous forms at elevated temperatures.
Copper Slag As Sand Replacement For High Performance Concrete"CCC, Volume 31, Issue 7, August 2009, Pages 483488 [3] Wei Wu. Weide Zhang, Guowei Ma," optimum content of copper slag as a fine aggregate in high strength concrete" Materials Design,Volume 31, .
Various proportions of copper slag replacement with sand (0%, 10%, 20%, 30%, 40% 50%) and partial replacement of fly ash with cement 30% in concrete revealed that the compressive strength of concrete cubes with 40% replacement of fine aggregate with copper slag shows an increase of 15% when compared to the normal concrete cube.
(replacement of sand by weight = 30% with Cast Iron Chips), 30% by weight of Blast Furnace Slag, replacing 30% of cement in the mix. The results recommend the use of Cast Iron Chips in concrete instead of sand use of Blast Furnace Slag instead of cement as well, up to certain level of replacement improves the
ferronickel slag as a substitute for aggregates N. Dimiglou a, Tsakiridis b, N. ... byproduct of the pyrometallurgical treatment of for the recovery of Ni as ferronickel; its laterites ... the influence of fly ash content and the replacement of crushed sand stone aggregate with concrete
A few studies have been published utilizing nickel slag for producing alkaliactivated cements. Bin et al. 78 produced alkaliactivated nickel slag cements with good mechanical performance, although the contents of CaO and Al 2 O 3 needed to be adjusted to increase reactivity in binder formation. Blocks were produced with these cements using nickel slag fractions with different finenesses, 79 ...
iii. The recommended % replacement of sand by copper slag is 40% iv. The addition of slag in concrete does not have any environmental problem. * Filtered sand and Sea Sand The use of filtered sand and sea sand have posed many challenges to the engineers as many of the concrete structures failed using the filtered sand and sea sand.
Jan 27, 2016· 3. T. Ch. Madhavi (2014) Copper Slag In Concrete As Replacement. The researchers found in his experiment that the copper slag is an industrial waste which can be used as a replacement for cement and sand and helps in increasing the mechanical properties of concrete.
Compare the strength in 40% replacement of copper slag at 7, 28, and 60 days. M. V. Patil, [3] investigated on Effects of copper slag as sand replacement in concrete, for this research work, M30 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to in concrete. Mr.
natural river sand as a partial replacement and waste limestone aggregates has been used in place of Coarse aggregates (Basalt stones) as the partial replacement. Steel Slag is the waste byproduct obtained from the iron and steel plants and Waste Limestone Aggregates are obtained from the Limestone quarries.
Brinda. D et al [4] investigated on various corrosion and durability tests on concrete containing copper slag as partial replacement of sand and cement. In this paper, M20 grade concrete was used and the tests were conducted for various proportions of copper slag replacement with sand of 0% to 60%, cement 0% to 20% and combination.
In pyrometallurgical recycling of EAF dust, the fume (, zinc oxide fume) generated is usually polluted by chlorine and fluorine (Tsugita, 2003), while the residue/slag produced often has a high iron content (Barna et al., 2000) and a small amount of nonferrous metals such as zinc and lead which can be recycled either in an electric arc ...
Copper slag, which is produced during pyrometallurgical production of copper from copper ores contains materials like iron, alumina, calcium oxide, silica etc. For every tonne of metal production about ton of slag is generated. Dumping or disposal of such huge quantities of slag cause environmental and space problems.
