Adsorption of copper and zinc with alkali-activated blast furnace slag from mine water [PDF]

, 2018
Metal contamination is an alarming problem near mining areas all over the world. Released wastewaters and mining water loose different metals to environment affecting lakes, rivers and other water sources (Jain and Das, 2017).

Alkali activation of fayalite slag

, 2017
In this thesis, alkali activation of fayalite slag was investigated. The slag utilized is a waste by product from nickel production, the activation of which resulted in the formation of a geopolymer binder of acceptable properties. The need for a reduction in overall waste output as well as the cementitious properties exhibited by this slag motivated ...

Reuse of aluminosilicate industrial waste materials in the production of alkali-activated concrete binders

, 2014
The use of alternative inorganic waste materials, other than fly ashes or blast furnace slag, in the production of alkali-activated binders is reported. Residues from industrial activities related to energy, metallurgy, mining, ceramics, construction and

Understanding the roles of activators towards setting and hardening control of alkali-activated slag cement

, 2019
Sodium silicate-activated slag often gives high early strength but sets too rapidly. Commercial retarders for Portland cement and partial replacement with other cementitious components in alkali-activated slag (AAS) system have been proven ineffective ...
