Jan 27, 2017· As this research is a parametric study to assess the effects of copper slag on various properties of concrete, we chose not to adjust the mix in order to get a fixed slump (e.g. by adjusting water content and using superplasticisers). Instead we systematically observed the changes in the slump of the mixes upon replacements of sand by copper ...

Copper Slag. Air-cooled copper slag has a black color and glassy appearance. As a general rule, the specific gravity will vary with iron content, from a low of 2.8 to as high as 3.8. (15) The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption of the material is typically very low (0.13 percent).
Copper slag is a by-product of copper extraction by smelting.During smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below.
copper slag is similar to the natural sand. The copper slag is chemically stable and physical properties are also similar to fine aggregate. The amount of copper slag is 20%, 40%, 60%, 80%, , was replacement of fine aggregate in cement mortar and concrete. Fine aggregate and copper slag fineness modulus was roughly 2.6 for concrete mix design.
ENVIRONMENTAL PERFORMANCE OF COPPER SLAG AND BARSHOT AS ABRASIVES A Thesis Submitted to the Graduate Faculty of University of New Orleans in partial fulfillment of the requirements for the degree of Master of Science in Environmental Engineering by Sandhya Naidu Potana B. TECH (Civil) Jawaharlal Nehru Technological University, 2001
Typically, the majority of its composition is iron oxide and silicon dioxide, formed when molten slag is quenched in cold water. This cooling process fractures the slag into coarse and angular particles, making it an ideal blasting slag with optimal blasting properties. Advantages Of Ebonygrit – Copper Slag.

A slag by-product of such workings was a colorful, glassy, vitreous material found on the surfaces of slag from ancient copper foundries. It was primarily blue or green and was formerly chipped away and melted down to make glassware products and jewelry. It was also …
Slag has similar properties to sand and is a very effective substitute during monsoon (rainy) season. Further, Copper Slag is also used in the production of cement, mortar, and concrete as a raw material for clinker, cement replacement, coarse and fine aggregates.
Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat. It …
Copper slag abrasive is dense enough to be reclaimed via a Cyclone separator in coarser sizes only. It has a 115 to 120#'s/cubic foot. THIS IS A HIGHER DENSITY THAN COAL SLAG AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL.
Since copper slag has a low content of CaO, granulated copper slag exhibits pozzolanic properties (Deja and Malolepszy, 1989, Douglas and Mainwaring, 1985). As CaO content increases or under the activation of NaOH it can exhibit cementitious properties and can be used as partial or full replacement for Portland cement.
