copper slag composition

In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Adapted from Piatak, N.M.; Parsons, M.B. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. Leaching tests on mechanically activated samples gives an idea of the resistance to leaching of the heavy metals even upon weathering. The absorption capacity of the material is typically very low (0.13%). Data from Piatak, N.M.; Parsons, M.B. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. The granulated slag (<3 mm size fraction) has both insulating and drainage properties which are usable to avoid ground frost in winter which in turn prevents pavement cracks. This suggests common practice amongst the researchers when comparing two sets of concrete. Returning to Table 4.3, where all the data have been deliberately presented in some detail so that the reader can perform his or her own analysis and evaluation and develop the use of this information in designing concrete mixes using CS. Copper slag, which is produced during pyrometallurgical production of copper from copper ores contains materials like iron, alumina, calcium oxide, silica etc. In Sweden (Skellefteå region) fumed and settled granulated copper slag from the Boliden copper smelter is used as road-construction material. The scientists lead by Prof. Alexandros Charitos have already been able to extract around 50 percent of the iron in this way, and thus verify that the copper slag, in principle, can not only be used in the steel, but also in the glass and mineral fibres industries. Dumping or disposal of such huge quantities of slag cause environmental and space problems. These studies demonstrated that high compressive strength cements can be developed via alkali-activation of copper slags; however, the leachability of heavy metals from these inorganic cements remains unknown, which might limit their applicability as building materials. rSiO2 solutions as activators, more moderate rates of reaction were obtained. http://dx.doi.org/10.1016/j.apgeochem.2014.04.009. This could have been caused by several factors relating to the mix proportioning, as well as the particle packing of aggregates in both sets of mixes, eliminating the advantage that could be accrued by the use of quenched CS as a cement constituent in the form of enhanced pozzolanic activity. Michigan Department of Transportation Specifications consider reverberatory copper slag to be a conventional coarse and fine aggregate for HMA pavement (Gorai et al., 2003). Effect of increasing air-cooled and quenched copper slag (CS) content on the compressive strength of concrete. Suitable for SA-3, … 0.009% Zinc (as Zn) : Approx. 2). The amorphous content of the copper slags is high, approximately 30%. Due to rapid cooling, the melt generally consists of a fine grained mixture of different phases (Fig. Numerous houses in the same region are built with a slag insulated foundation.[3]. EC number: 266-968-3 | CAS number: 67711-92-6 | CAS number: 67711-92-6 In addition to the copper and iron main components of the system, trace elements like antimony, gallium, germanium, gold, indium, and silver were added in experiments that spanned the temperature range of 1473–1573 K (1200–1300 °C). By continuing you agree to the use of cookies. Clearly, given the information available in the literature, there is scope for a fundamentally important study to be conducted to investigate the amorphous nature of the quenched glass and its pozzolanic reactivity, the variability attached to it and what benefits, if any, can be derived from it. Overall impression of the effect of copper slag on the strength of concrete. Characteristics and utilization of copper slag—a review. This elucidates that it might be possible to utilize existing stockpiles of copper slags for producing alkali-activated cements, and to contribute to remedying some of the existing environmental issues associated with the disposal of these slags.
