copper slag as a substitution replacement material of sand. Copper slag which is an industrial waste product can be used as replacement for cement with sand and contributes to the increase in various mechanical properties of concrete. Copper slag can be used up to 30% but when used ead of 50% results in decrease in strengths. [13]
1/8/2009#0183;#32;The results indicate that there is a slight increase in the HPC density of nearly 5% with the increase of copper slag content, whereas the workability increased rapidly with increases in copper slag percentage. Addition of up to 50% of copper slag as sand replacement yielded comparable strength with that of the control mix.
The specific gravity of sand and copper slag was amp; respectively as shown in Table The water absorption of 20 mm coarse aggregates, sand amp;copper slag was found to be, and respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is
copper slag is produced from these industries [12, 13 amp; 15]. Copper slag has high density and specific gravity and has low water absorption than sand. Copper slag is finer than Sand. But it satisfies zone 1 grading limit. If copper slag is replaced by sand, free water content in concrete is increased due to its low
concrete with partial replacement sand by copper slag to determine the optimum percentage of copper slag to be used in concrete to attain good strength. The effect of replacing fine aggregate with copper slag on the Workability, Compressive Strength, Split Tensile Strength, Flexural Strength, Density,
A series of tests were performed to investigate the effect of copper slag as partial replacement of fine aggregate on corrosion processes and behavior in prism specimens. Chloride migration tests in steadystate were executed at the age of 28 and 91 days in accordance with Japan Society of Civil Engineers (JSCE) G to determine the diffusion coefficient of chloride ions permeated
This paper presents the results of an experimental investigation on the properties of concrete using copper slag as partial replacement of fine aggregate. For this research work, M20 grade concrete was used and tests were conducted. Various concrete mixtures were prepared with different proportions of copper slag as fine aggregates replacement.
7/11/2020#0183;#32;The copper slag is a byproduct of copper manufacturing process, which is available in very large amount. Also the stone industries in Marashtra pro
1/12/2017#0183;#32;Evidently, the compressive strength increased by about 22%, 10%, 15%, 23% and 21% for 40% replacement level of slag (M2) at curing ages of 1, 3, 7, 28 and 90 days, respectively, compared to the control mix (M1), while the increase in compressive strength was 26%, 19%, 27%, 32% and 30% upon replacing sand by 80% slag (M3).
Effect of Copper Slag as a Sand Replacement on the Properties of Concrete. No 4, 2011 Performance of Copper slag and ferrous slag as partial replacement of sand in Concrete .
granulated copper slag does not pave away for leaching of harmful elements like copper and iron present in slag. The percentage replacement of sand by granulated copper slag were 0%, 5%, 10%, 15%, 20%, 30%, 40% and 50%. The compressive strength and split Tensile Strength will increase.
increased by the replacement of Msand by copper slag, saves concrete material cost. Here we are using OPC of 53 grade, Well graded coarse and fine aggregate. 30% copper slag replacement showed Maximum workability. The workability of concrete had been found to decrease after 30% in concrete.
Bottom Ash and Copper Slag. Mix design and sample preparation Concrete mixtures with different proportions of Copper slag used as a partial or full substitute for fine aggregates were prepared in order to investigate the effect of Copper slag substitution on
Experimental Study on Partial Replacement of Copper Slag and Flyash for Fine Aggregate and Cement and PVA Fiber As Reinforcement in Concrete A. Anbarasan 1, To investigate the effect of sand, copper slag super plasticizer amp; PVA fibers on the behavior of our concrete. IV. INGREDIENTS OF CONCRETE The concrete composed of cement, sand, fly ash
Effect of Copper Slag (20%, 25% and 30%) with various proportions of mix by the partial replacement of sand and gravel respectively. It also suggested that the determination of the copper
copper slag can be used as a partial replacement for sand as fine aggregate in concrete up to 40% in pavement grade concrete with out any loss of cohesiveness and the compressive and flexural strength of such concretes is about 20% higher than that of conventional cement concretes of the same grade
This paper presents the results of an experimental investigation on the properties of concrete using copper slag as partial replacement of fine aggregate. For this research work, M20 grade concrete was used and tests were conducted. Various concrete mixtures were prepared with different proportions of copper slag as fine aggregates replacement.
Abstract This paper reports the effect of concrete using copper slag as replacement of fine aggregate. In this project work, M25 grade of concrete was taken for concrete mix design. The properties and characteristics of materials for cement, fine aggregate, coarse aggregate and copper slag was studied for concrete mix design.
