Cement paste and cemented tailing backfill samples that without or contain Cu-Ni slag with various grinding times were made and cured at 20°C for 7, 28, and 150 days. Mechanical test and microstructural analyses are performed.
Doniambo processes nickel ores from four different mine sites in New Caledonia (Filer and Le Meur, 2017). From an economic viewpoint, the wish to process more nickel ores locally is rational: it would generate greater added value and address island unemployment (14.7% in 2014 according to ISEE, 2016), particularly for low skilled labour. For a ...

A copper-nickel slag-based alkali-activated cementing material (CN) for backfilling was prepared using copper-nickel slag as a raw material and sodium silicate (SS) as an activating agent. The effects of SS content (6%, 8%, and 10%) and curing humidity on the compressive strength of CN were investigated using an electronic universal testing machine.
