copper slag as sand

This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were plastered.

copper slag had a significant effect on the unconfined compressive strength (UCS). For cement stabilized specimens, the improvement impacts of the copper slag on the UCS was more tangible than unstabilized ones. Furthermore, an increase in the UCS was most apparent in the 2% cemented specimen wherein the UCS increased more than 78% as the copper slag increased up to 20%. Moreover, it was ...

investigations are carried out by replacing the sand with copper slag in proportions of 10%, 20%, 30%, 40%, 50%, 60% and 100% keeping all other ingredients constant. It was seen that the optimum content of copper slag is 40% beyond which the strength starts decreasing. Patil et al. (2016), this work investigates the effect of copper slag as sand replacement in concrete. This paper presents the ...

Figure 1: Particle size distribution of copper slag compared to the sand used in the tests . CEST2015_00437 3. Experimental results Slump test As mentioned above, a possible anticipated difficulty when using aggregate other than that recommended for concrete could be the effect on the workability of the fresh concrete. Slump tests were performed according to BS EN 123502:2000 (BSI, .

01/01/2018 · Natural sand, as well as copper slag, was passed through mm IS sieve. The specific gravity of natural sand and copper slag was experimentally determined to be and, respectively, by using pycnometer as per BIS:2386 part III1963, R 2002 [17]. Coarse aggregates (basalt) of size 10 mm and 20 mm having a specific gravity of and ...

Copper slag was used as a replacement of sand from 0 to 100% at an interval of 20%. Copper slag was obtained from Taj Abrasive Industries loed in Sikar, Rajasthan, India. Fig. 1 demonstrates particle size distribution of sand and copper slag and Fig. 2 (a) and (b) shows sand and copper slag respectively used in this investigation. The ...

Copper Slag as partial replacement of sand in SFRC and Conventional Concrete and results are compared. Objectives Investigating the developments in mechanical properties of concrete due to addition of hooked end steel fibers and replacement of copper slag with varying percentages of parameters of steel fiber reinforced and conventional concrete due to replacement of .

Effects of Copper Slag as Sand Replacement in Concrete. The specific gravity of sand and copper slag was respectively as shown in Table The water absorption of 20 mm coarse aggregates, sand copper slag was found to be, and respectively. It was found that water absorption of copper slag was very low as compared ...

The percentage of Copper Slag(CS) added by weight in a range viz. 0, 25, 50, 75 and 100% as a replacement of sand used in concrete and cement was replaced with 15% Metakaolin. The properties studied include compressive strength, splitting tensile strength, Sorptivity, Rapid Chloride Permeability Test (RCPT), Accelerated Carbonation test and Microstructural properties. The test results showed ...

Copper slag as sand replacement for high . 200981 Copper slag has a specific gravity of which is higher than that for sand () and OPC () which may results in production of HPC with higher density when used as sand substitution. Also, the measured water absorption for copper slag was % compared with % for sand. Read More Copper slag as sand replacement for high . This ...

Although the majority of the produced copper slag is used in the sand blasting industry and in the manufacturing of abrasive tools, the remainder is disposed without any further reuse or reclamation. There are many mechanical and chemical characteristics that qualify copper slag to be used in the concrete as partial replacement of Portland cement or a substitute of aggregates. For example ...

Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of fine aggregates. For this research work, M50 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0, 20%, 40%, 60%, 80%

23/10/2013 · Using waste copper slag (CS) as a replacement for sand in concrete mixture is becoming popular in Singapore and around the world. What are the consequences of this material substitution? Will this result in lower environmental impact? This work used attributional and consequential life cycle assessments to evaluate the net results of replacing sand with CS. Impacts were assessed with .
