New residue-free processing of copper slag from smelter
The use of the calcium silicate-the residue of copper slag after leaching of metals as a cement additive (Product 2) is also particularly attractive, unlike fine ground slag in its original state which the mixing ratios are limited by the metal content because of the metals elution exclusion.

Investigation of gamma ray absorption levels of composites
Although there are very few studies on this subject, the main materials studied are by-products, such as ground granulated blast furnace slag, silica fume, foundry sand, cement kiln dust, and fly ash used as substitutes for cement [3, 36, 37, 75,76,77]. Among the various additives, fly ash is the most suitable due to its pozzolanic structure.
