Jan 14, 2015 · The present study reports the properties and hydration of blended cements with ferronickel slag, produced during the pyrometallurgical treatment of laterites for the production of ferronickel. For that purpose, the slag was ground to a specific surface area of 4,000 cm2/g and added in ratios 5, 10, 15, and 20 wt%. The produced blended cements were tested by determining their ...
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield desired reactive cementitious characteristics when ...
