  • Properties of blast-furnace slags containing high amounts

     · Mortars containing slag S 1 exhibit better strengths up to 7 days of hydration than mortars containing slag S 4.The increase in Blaine fineness has no influence on the hydraulicity of slag S 4.Whatever the cement content is the strengths remain low for mortars containing slag S 4 within the first 7 days of hydration. Slag S 4 seems to inhibit cement hydration at early age.
