United States Oman Bangladesh We can supply you with copper slag (low Cu content) in good quantity. GGBFS or GBFS is the most used raw material in cement industry to make slag cement. Lightweight fill Raw material for the manufacture of glass GBFS can be used as a substitute for sand in building materials GGBFS can be used as
replacement for Portland cement. The use of copper slag in the concrete as a replacement for fine aggregate, reduces the costs of disposal, lowers the cost of the concrete and also helps in protecting the environment. Despite the fact that several studies have been reported on the effect of copper slag on the properties of Concrete,
Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated longterm performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
Many researchers had already found, copper slag possible to use as a material in concrete. In this experimental study copper slag is used in concrete as replacement material of fine aggregate. For this study, M40 grade of concrete is used and the tests are conducted for various replacement of fine aggregate using copper slag as 0%, 20%, 40%, 60%,
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
It is recommended that up to 25% of copper slag on weight basis can be used as replacement of sand in order to obtain concrete with good properties. It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of
mixes with copper slag gave concrete with adequate properties, with the optimal sand replacements by watercooled copper slag overall being in the region of 3060%. Based on the results watercooled copper slag can be considered to be a suitable candidate for the partial replacement of
Replacement of copper slag in fine aggregates reduces the cost of making concrete. Replacement of copper slag increases the self weight of concrete specimens to the maximum of 15 to 25%. 25% addition of copper slag as fine aggregate in concrete gives more strength compare to 30% addition of copper slag as fine aggregate in concrete.

Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on the performance of OPC and PSC. The users of copper slag in OPC / PSC can be assured of the nonleachability of
Results showed that replacement of 40% of fine aggregate with copper slag caused major changes on concrete strength, the strength increase about 36% .Further increasing the ratio of copper slag as fine aggregate reduced the concrete strength and increased concrete slump .
Effect of copper slag on the hydration of cement based materials is studied. Up to 15% by weight of copper slag was used as a portland cement replacement. Activation of pozzolanic reactions were studied using up to % hydrated lime. Hydration reactions were monitored using quantitative XRay diffraction (QXRD) and the porosity was examined using mercury intrusion porosimetry (MIP).
Dec 01, 2020#0183;#32;Furthermore, copper slagPortland cement mortars with the substitution of 25% (by weight) of cement by copper slag and alkaliactivated slag mortars cured at 20 and 65 #176;C were made, to
Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or a...
Jun 11, 2020#0183;#32;Up to 15% by weight of copper slag was used as a portland cement replacement. Hydration reactions were studied through semiquantitative Xray diffraction and TGA/DTA. Samples of copper slag and hydrated lime (ASTM type S) were used to test the pozzolanic properties of the slag. The porosity was examined using mercury intrusion porosimetry.
varying proportions of copper slag (CS) with fine aggregates by 0%, 10%, 20%, 30%, 40% and Egg shell powder (ESP) as cement by 0%, 7%, 14%, 21%, 28% by weight. The obtained results are going to be compared with the traditional concrete, there by knowing the changes within the properties of concrete containing copper slag as a partial replacement of fine aggregates and eggshell powder by cement
Jul 08, 2019#0183;#32;Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturallyseparating layers. One layer is a waste containing iron and silica compounds and is discarded as slag slagByproduct left after a desired metal is thermally separated from its raw ore.. Approximately 75 percent of the copper concentrate ends up as slag.
Test results shows that the strength properties of concrete has improved having copper slag as a partial replacement of Sand (upto 40%) in concrete however in terms of durability the concrete
Aug 01, 2009#0183;#32;The effect of copper slag replacement as fine aggregates on the workability and density of high performance concrete is presented in Table 2 for different proportions of copper slag. The workability of concrete was assessed based on the measured slump of fresh concrete. It is clear from Table 2 that the workability of concrete increases significantly with the increase of copper
