aggregate with copper slag to increase the strength parameters such as compressive strength, split tensile strength, and flexural strengths of the M30 concrete. Here the fine aggregate partially replaced by copper slag (CS) in 20%,30%,40% and 50% by weight of .
The amount of corrosion is also found to be minimum, at 60% copper slag replacement for fine aggregate compared to that of the control specimens. 5.

[PDF]copper slag has been carried out. It was found that as the fineness modulus of copper slag increased, the compressive strength value of concrete in which cement was partially replaced by copper s lag, decreased to some extent. Detailed results have been depicted in the later part of this paper.

[PDF]corrosion of partially copper slag in pdf 2.1.4 Copper Slag The copper slag used in this study is obtained from Sterlite industries, Tuticorn. This material replaces fine aggregate in mix proportion. The copper slag used in this study confirms to zone II. Table 4 and Table 5 show chemical and physical properties of copper slag respectively.
[PDF]There is a range of partially oxidised sulphur species (e.g. thiosulphate, dithionate etc.) and reduction of one or more of these species can be the principle cathodic reaction in corrosion e.g. in sour process brines in the oil and gas industry. Under uncoupled corrosion the anodic and cathodic reactions occur at small, local areas on the metal.
[PDF]The results showed that by partially replacing copper slag for fine aggregate in self compacting concrete would not have any poor effects on its workability and durability properties. Key word: Copper slag, Durability, workability, packing factor, corrosion.
[PDF]Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper concentrates now available. The global production of refined copper over the past eight years is ...

[PDF]the concrete is a fundamental characteristic of steel corrosion resistance. Corrosion caused by the action of sulfur dioxide and sulfuric acid in reinforced concrete can be of three types: chemical corrosion which leads to the deterioration of concrete itself and electrochemical and electrolytic corro-
[PDF]Increased corrosion resistance can also come about by the use of concrete additives. Silica fume, fly ash, and blast-furnace slag reduce the permeability of the concrete to the penetration of chloride ions. Corrosion inhibitors, such as calcium nitrite, act to prevent corro- sion in the presence of chloride ions.

[PDF]SIIL is the producer of copper slag (Figure 1.1) during the manufacture of copper metal. Presently, about 2500 tons of copper slag is produced per day and a total accumulation of around 1.5 million tons. Figure 1.1 Appearance of copper slag sample. This slag is currently being used for many purposes.
[PDF]Then copper slag is replaced by 20 %, 40 %, 60 %, 80 % and 100 % of sand simultaneously with mineral admixture i.e., 5% to 30% of cement in the increment of 5 percent to study compressive strength, density, split tensile strength and corrosion properties.
Jan 27, 2017 · It can be observed that both control mixes (of w/c ratios of 0.45 and 0.55 respectively) had a higher corrosion (based on the higher mass loss of the bars) than the mixes with copper slag. The highest corrosion was found for the 0.45 control mix which also showed some surface cracking of the concrete adjacent to the reinforcing bar.

with M-sand, natural sand and copper slag concrete. Natural fine aggregate is completely replaced by M-sand and partially by copper slag. Compressive strength is evaluated and compared up to 28 days of ages. Specific properties of concrete materials and copper slag are also studied. The entire tests were performed as per specifications.
