how is water slag powder produced

Slag Hydration

The slag surface is first covered by Portland cement hydrates, then attacked by Ca 2 + ions from the super saturated solution, producing the ''inner'' hydrate. The dissolution of Ca 2 + and Al 3 + ions from slag leaves a skeleton hydrated layer, which transforms gradually into inner hydrate by the supply of Ca 2 +.
