Jun 06, 2011· This paper reports a laboratory study investigating the use of granulated copper slag as a fine aggregate in hot-mix asphalt concrete. Marshall-mix design was performed on different blends of aggregate containing up to 40% copper slag.
A Guide to the Use of Steel Furnace Slag in Asphalt and Thin Bituminous Surfacings 1 1.1 Purpose of the Guide. This Guide, which is supplementary to the Association's Guide to the Use of Slag in Roads, reviews in detail the use of steel furnace slag in asphalt and thin bituminous surfacings. The Guide shows that, with technical evaluation
Coal slag is by-product of coal-burning power plants, considered a "green" abrasive because it would otherwise be disposed of as waste. It is a relatively cheap, low dusting abrasive with low free silica, but is considered a dirty abrasive and not widely used in wet abrasive blasting because the high amount of "fines" (fine particles ...
Nov 30, 2018· Close to 19 million tons of copper are produced annually worldwide. When this primary material is obtained at a concentration between 2 and 2.5 tons of copper slag (CS) per ton of produced copper, this translates into an estimated annual production of close to 42 million tons of copper slag, .
Request PDF on ResearchGate | Effect of copper slag on performance of warm mix asphalt | Copper Slag (CS) is a by-product obtained during the matte smelting and refining of copper. It is ...
copper slag in mixes. Although adding copper slag had negative effect on indirect tensile strength of mixtures, the tensile strength rate (TSR) value emproved by replac - ing CS in the mixtures [Hassan and Al-Jabri, 2010]. In this research, the usability of copper slag in warm mixed asphalt concrete was investigated in order to bear the
The incorporation of copper slag (CS) in asphalt pavements proves to be a good substitute in replacing the natural aggregates. This reduces pavement construction cost and plays a key role in protecting the environment. The CS can be used with Recycled Asphalt Pavement (RAP) material especially in Warm Mix Asphalt (WMA) pavements.
a basalt and copper slag from Wisconsin, flint from Oklahoma, three varieties of calcined kaolin from Georgia, three varieties of quartz (from Ohio, Washington, and Maryland), and feldspar mineral from Wyoming. Two replicates were made for each aggregate. The surface of each 20x20-inch asphalt test slab was covered with an
Steel slag, air-cooled blast furnace slag, nickel slag, and copper slag are not acceptable for use in HMA. RAP containing steel slag is not permitted. RST containing asbestos is not permitted. Post consumer shingle material is not permitted. If one or more of the aggregates to be used in the mix requires an anti-stripping agent, then all aggregates
The potential of copper slag as a replacement for fine aggregates in bituminous mixes was also investigated. It was concluded that a mixture of copper slag, fly ash, and soil has the potential for use in embankment, subbase, base, and wearing courses of road pavement.

This paper reports a laboratory study investigating the use of granulated copper slag as a fine aggregate in hot-mix asphalt concrete. Marshall-mix design was performed on different blends of aggregate containing up to 40% copper slag.
Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.
I 'm doing some research about the influence of copper slags in WMA. The results show that copper slag has negative effect on Asphalt properties, such as marshall stability, creep stiffness and ...
Abrasive blasting, also known as grit blasting or sandblasting, utilizes blast equipment to propel a wide range of blasting media and grits including coal slag, copper slag, crushed glass,aluminum oxide, steel grit and garnet. Abrasive blasting has been in use for over a century.
surface layers. At the same time, the expansion of asphalt roadways results in the production of a large amount of asphalt road waste, known as reclaimed asphalt pavement (RAP). This paper aims to investi-gate the feasibility of the use of copper slag and recycled concrete aggregate (RCA) as .
The use of copper slag aggregates in hot mix asphalt pavements was investigated by Transportation Research Board, Washington (Collins and Cielieski, 1994). Fine copper slag has reportedly been used in hot mix asphalt pavements in California and granulated copper slag has been incorporated into asphalt mixes in Georgia to improve stability.
Copper Slag (CS) is produced as waste from roasting of copper, in which sulphur (as SO 2) is eliminated. CS was used as fine aggregate (up to 30%) in the .

N2 - Copper slag (CS) is a by-product of the copper extraction process, which can be used as coarse and/or fine aggregate in hot mix asphalt (HMA ...
Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include. Blending with many other products such as granulated slag, fly ash and lime to form pavement material, skid resistant asphalt aggregate and unconfined construction fill.
Traction is important when sealcoating parking lots or driveways. Our copper ore slag is a thru-and-thur black product unlike sand, and it's a fantastic abrasive that works even better than sand, giving maximum adhesion. Come check how you can get an ore slag for your next sealcoating project.
