The mix 0% copper slag had a slump of 25mm while the mix with 100% copper slag had 82mm. These results can be due to the low water absorption of copper slag (0.16%) compared to sand (1.25%). Based on strength, copper slag aggregate provides a great alternative to sand. For maximum strength a 100% replacement of copper slag for sand is ideal.

Matte is a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper, nickel, and other base metals. [1] Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting ) to produce blister copper ...
Although many abrasives used in blasting rooms are not hazardous in themselves, (steel shot and grit, cast iron, aluminum oxide, garnet, plastic abrasive and glass bead), other abrasives (silica sand, copper slag, nickel slag, and staurolite) have varying degrees of hazard (typically free silica or heavy metals).
Non-ferrous slag can be characterized into copper, lead, and zinc slags due to the ores' compositions, and they have more potential to impact the environment negatively than ferrous slag. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores ...
