Copper Slag Concrete

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. Copper slag is just one of many different materials that may be used as abrasive grit. Rate of grit consumption, amount of dust generated, and surface finish quality are some of the variables affected by the choice of grit material.

It is found that water absorption of copper slag is very low as compared with the natural sand and it affects on workability of concrete. Results from specific gravity and water absorption tests revealed that copper slag has a specific gravity of

25-05-2020· Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. When added to concrete, it makes the paved surface less porous, which minimizes problems with moisture and freezing. It also makes concrete more fire resistant, and helps to slow the spread of heat and flames.

Copper slag is a by-product formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top. The molten copper slag is then drained off and quenched with water or left in the air to cool. In Singapore, treated and processed copper slag (Mohs Hardness ≥6) is imported from various

This work 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. Three masonry wall panels of dimensions 1 × 1 m were plastered.

30-07-2020· The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast …

Utilization of copper slag in cement and concrete. 5. Use of copper slag in cement clinker production. As shown in Table 1, copper slag has a high Fe content and has been used as an iron adjustment material during the cement clinker production (Huang, 2001).Since the main composition of copper slag is vitreous FeSiO 3, it has low melting point and could reduce the calcination temperature for ...
