“…Singh et al (2014) studied the effect of partial replacement of fine aggregates by CS, they found that for all evaluated setting times, compressive and flexural strength were higher or similar to control concrete. Madheswaran et al (2014) studied the use of CS in building construction as partial replacement of sand in cement concrete. They reported an increase on density, workability and compressive strength with CS additions of 50 wt% for conventional concrete, and 75% for high strength concrete.…”

The use of copper slag (CS) as fine aggregate and partial substitute of cement for mortar preparation was studied. Results showed an increase on compressive and flexural strength at 3, 7 and 28 days using CS as fine aggregate. As partial replacement of cement, a gradual improvement on compressive and flexural strength at 7, 28 and 90 days was noticed. At 7 and 28 days, the control mortar (CM) shows higher compressive strength and flexural strength. Nevertheless, at 90 days, the CM and mortars prepared with CS showed similar compression and flexural strength. The use of CS in the construction industry is hence presented as an auspicious alternative for improving the quality of mortars and mitigating the environmental impacts of slag deposits, adding extra value on this metallurgical waste and reducing the shortage of aggregates of northern Chile.

“…Replacement of copper slag in both fine aggregate and cement replacement reduces the cost of making concrete. [7] (2012), This paper 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.…”

Conservation of natural resources and preservation of environment is the essence of any modern development. In last few decades, construction activities increase rapidly. Itsss require more raw materials and it will result in shortage of material in future. Now a days there is trend of recycling and reusing material, which is partial solution of this problem. Also, Industrial wastes are used as raw material. It reduces the consumption of natural resources. Copper slag and recycled aggregate are the industrial waste and recycled material used as a fine aggregate in concrete. Both the material has same physical properties similar to the fine aggregate. By replacing 10% to 50% copper slag as fine aggregate, concrete produced. At the optimum content of copper slag, 10% to 50%of recycled aggregate replaced and the concrete produced.

“…The review study reveals that the using different alternatives for river sand produce better results than conventional concrete. Madheswaran et al [7] where studied the concrete properties with two water cement ratio and different proportion of copper slag ranging 0-100% of fine aggregate. Finally study reveals that copper slag provides better performance in workability and strength aspect.…”

The overuse level of cement and natural sand for civil industry has several undesirable social and ecological consequences. As an answer for this, industrial wastes called as by-products (pozzolanic materials) such as fly ash, GGBFS, silica fume and metakaolin can be used to interchange partially cement and natural sand by manufacturing sand (M-sand). In this paper, the detailed experimental investigation was done to study the effect of partial replacement of, natural sand by M-sand in various percentages (0%,10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%), with water-cement ratio of 0.45 and cement was partially substituted by 20% of pozzolanic materials. M30 grade of concrete mix proportions were designed as per IS 10262:2009 guidelines. The fresh concrete properties and tensile strength results, were checked for the different concrete mix proportions and compared with conventional concrete. The tests on hardened concrete were destructive in nature which includes tensile test on cylinder as per IS: 5816-1999 at 28 days of curing. From this research work, it can be concluded that for replacement of 60% natural sand by M-sand and 20% cement by silica fume yields maximum tensile strength and improves the microstructure than conventional concrete.
