Mar 19, 2019· Contractors may also use copper slag in place of sand during concrete construction. The slag serves as a fine, or binding agent, which helps hold the larger gravel particles within the concrete together. When used in this manner, the slag helps to improve the properties of the concrete, and also serves as a form of recycling.
• Copper Slag: Copper slag is an individual by product material produce by copper smetting and refining processes. This has similar property of sand, hence copper slag can be replaced for fine aggregate. The physical Properties of natural sand and copper slag is as below.
cost of cement and sand with concrete mix grade M20 by studying the mechanical behavior of this concrete mix by partial replacing with such as FlyAsh, Copper slag and GGBS in concrete mix. In this study, partial replacement of Cement with FlyAsh and Sand with Copper Slag and coarse aggregate with GGBFS considered.
The replacement of fine aggregate using copper slag in concrete increases the density of concrete thereby increases the selfweight of the concrete. The workability of concrete increased with the increase in copper slag content of fine aggregate replacements at same watercement ratio.
with copper slag in concrete. The primary test on flexural behaviour of beams is conducted on the partially replaced concrete, to determine the possibility of using copper slag as a replacement of sand in concrete. The test results of concrete are obtained by replacing copper slag to sand in various percentages ranging from 0 to 60 percentages.
CONCLUSION From the present study, following conclusions were drawn After 28 days of curing, it is observed from the work that for all percentage replacements of fine aggregate by Copper slag and cement by mineral admixtures, (SF, MK, RHA, FA, GGBFS), the compressive and split tensile strengths of concrete are more than conventional concrete up to certain percentage replacement.
Jan 06, 2018· the control mix ( sand) at 56 and 90 days of curingThe volume of permeable voids decreased with the replacement of 4050% copper these results, it was found that copper slag in ...
•Replacement of copper slag ( replacement with sand)increases the self weight of concrete. specimens to the maximum of 1518%. • The initial and final setting time of copper slag admixed concrete is higher than control concrete. • Water absorption of copper slag was % compared % for .
The replacement of of fine aggregate by copper slag decreases water absorption by %, chloride ion permeability up to % and pH value by (Venu Malagavelli, 2010) studied the characteristics of M30 grade concrete with partial replacement of cement by GGBS and sand with ROBO sand (crusher dust).
Mar 30, 2019· Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent. Among the measurable improvements are higher workability, higher finishability, lower permeability, improved resistance to aggressive chemicals, more consistent plastic and hardened properties,...

Study on the partial replacement of fine aggregate using . concrete made with partial replacement of fine aggregate using for natural fine aggregate include blast furnace slag, manufactured sand
copper slag as a replacement of fine aggregate on the strength properties. The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive tiles, glass, rail road ballast, asphalt pavements. Despite increasing
The work reported in this paper is based on a laboratory study carried out to investigate the feasibility of using copper slag, a byproduct of copper refineries, as a partial replacement of sand in the preparation of pavement quality concrete (PQC) and dry lean concrete (DLC) mixes. A control mix for PQC was prepared with 400 kg/m3 of ordinary Portland cement (OPC) and water–cement (w–c ...
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% in concrete, to study the strength properties, compressive strength for curing periods of 7, 28, 56 90 days, Flexural strength and split tensile strength for curing periods ...
compressive strength increased with increase in copper slag content up to a replacement level of 50%. The maximum increase in compressive strength was observed at a replacement level of 40%. Beyond the replacement level of 50% of sand with copper slag in concrete, a .
Industries as a replacement for sand in concrete mixes. They concluded that the percentage replacement of sand by copper slag shall be up to 40% and compressive strength was increased by about 3540% and split tensile strength by 3035%.
Granulated copper slag is more porous and, therefore, has particle size equal to that of coarse sand. In this paper, a review of the previous research studies carried out by various researchers on utilization of copper slag in geotechnical applications is discussed and presented.
