What is the specific gravity of copper slag?

about 3.5 g/cm3
13.3. The density of copper slag varies between 3.16 and 3.87 g/cm3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm3, which means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.

What is copper slag used for?

Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece.

Why copper slag is used in concrete?

Copper slag can be utilized as fine aggregate in cement mortars, normal concrete and also as aggregates (coarse) in concrete (high strength). As fine aggregate in cement mortar, copper slag provides good interlocking leading to better volumetric and mechanical quality of different mixes.

How hard is copper slag?

No. 1 Blasting Material in Europe, made in EU, multifaceted particles, vitreous amorphous slag, 7.5 Mohs Hardness. Increased efficiency, up to 30% higher than any other similar agent for outdoor blasting, on almost any type of surface, indoor and outdoor.

What is the formula of copper slag?

The chemical composition of copper slag depends on the type of the ore source and copper manufacturing process, but usually consist of iron, silicon, aluminium and calcium oxides, in the proportion range of FeO: 30–40%, SiO2: 35–40%, Al2O3: 0–10%, CaO: 0–10%, and Cu: 0.5–2.1% (Gorai et al., 2003).

Is copper slag toxic?

This might not be such a good idea, however, since slag produced in refining copper, zinc, cadmium and other base metals can contain significant concentrations of a number of potentially toxic elements, including arsenic, lead, cadmium, barium, zinc and copper, Michael Parsons, a graduate student in geological and …

Can slag be used for anything?

Slags are one of the most natural products of all. Due to its positive technical characteristics, LD slag is used all over the world in road and railway construction and for engineering. The most common use is as an aggregate in the manufacture of asphalt. It is also successfully used as an aggregate for concrete.

Is copper slag flammable?

FLAMMABLE CLASS: This product is non-combustible. GENERAL HAZARD: None known EXTINGUISHING MEDIA: Use fire-extinguishing media appropriate for surrounding materials.

What is copper cement?

Cement copper (precipitated copper) is a product obtained by precipitation (cementation), i.e., by adding iron to the aqueous solution resulting from the leaching of certain ores or waste. It is a finely devised black powder containing oxides and insoluble impurities.

What is in fly ash?

Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler. Bottom Ash, a coarse, angular ash particle that is too large to be carried up into the smoke stacks so it forms in the bottom of the coal furnace.

Is copper slag environmentally friendly?

Copper slag is an economical, established and the most widely accepted alternative to the natural aggregate (sand, crushed from natural rocks). Copper Slag is an eco-friendly industrial by-product being manufactured in Sterlite Copper, Tuticorin.

Can you use slag under concrete?

Steel slag is not recommended for use in rigid confined applications – such as concrete aggregate, base or fill under structures or floor slabs, or backfill against structures or bridge abutments. Shape and Texture: Steel slag is a crushed product having hard, dense, angular and roughly cubical particles.
