obtained when fine aggregate is replaced with copper at 40%. The least compressive strength of 88.49MPa is obtained when fine aggregate is replaced with copper slag. Now keeping this copper slag mix as constant, Nano silica is replaced with cement in various percentages i.e. 1%, 2% and 3%.


It is formed by leaving out some or all of the fine aggregate (fines). The remaining large aggregate then is bound by a relatively small amount of Portland cement . When set, typically between 15% and 25% of the concrete volume is voids, allowing water to drain at around 5 gal/ft²/ min (70 L/m²/min) through the concrete.


Theoretically the maximum value is 1.0, if the fresh concrete has achieved maximum compaction. Realistically, a value close to 1.0, like .95 or .98 is more likely. • The compaction factor of concrete in which fine aggregate is replaced by ferrochrome slag is found 0.88 and0.92 showing midway workability for concrete items.


The slump of the concrete incorporating the copper slag as fine aggregate increased as more natural sand was replaced by copper slag. Maximum slump obtained was 40mm which occurred at the copper slag replacement as compared to slump of concrete mix. In general, it can be concluded that addition of copper slag


(1) If fly ash is used for partial replacing cement in concrete making, it seems to be necessary to replace fine aggregate also by copper slag, ensuring that not both ratios (namely, fly ash cement or copper slag sand) exceed 1.0.

When Copper is being extracted from it's Ore, a significant amount of unusable residue is separated called as Copper Slag. This Slag more or less possesses the properties of copper upto some extent. Therefore it can be said to have more strength over futile fine aggregate replacement such as fly ash or rice or even pumice.

segregation, bleeding, and to improve flow. Copper slag (CS) is known for its excellent soundness, abrasion resistance, and stability. When compared to Sand, Copper Slag has a lower water absorption capacity. Copper slag is analogous to river sand in terms of behavior. The use of Copper Slag as a Fine Aggregate in concrete mixes lowers


Cement - Wikipedia A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is ...


The sand-pouring cylinder is calibrated using the following steps. The sand-pouring cylinder is filled with uniformly graded sand (passing 600 μ sieve and retained on 300 μ sieve) up to a height of 10 mm below the top.The mass of the sand-pouring cylinder filled with sand is recorded as M 1.The sand-pouring cylinder is then placed over a plane surface and …

It was found that


In this work, a detailed investigation has been carried out on the industrial by‐products such as fly ash (FA) and copper slag (CS) to find the suitability of suitable alternative materials for cement and fine aggregate. For every tonne of copper metal production, about 2.2 tonnes of slag has been generated.

Fly ash - Wikipedia

Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) – plurale tantum: coal combustion residuals (CCRs) – is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called ...


The addition of copper slag has improved the flexural strength of concrete. While replacement of copper slag in concrete increases, the density of concrete increases. It was observed that the partial replacement of copper slag as fine aggregate greatly increased the compressive strength at 20%, 40% and 60%.
