granulated slag nickel

Nickel Slag - an overview | ScienceDirect Topics

Granulated nickel slag is essentially an angular, black, glassy slag “sand” with most particles in the size range of − 2 mm (No. 10 sieve) to + 0.150 mm (No. 100 sieve). It is more porous, with lower specific gravity and higher absorption, than air-cooled nicked slag. Nickel slag is very abrasive and does not lend itself well to grinding.

Alkali Activation of Copper and Nickel Slag Composite ...

Alkali-activated copper and nickel slag cementitious materials (ACNCMs) are composite cementitious materials with CNS (copper and nickel slag) as the main materials and GGBFS (ground-granulated blast-furnace slag) as a mineral admixture. In this paper, the activity indexes of CNS with different grinding times were studied using CNS to replace a portion of cement.
