Abstract
This study investigated the interplay between sulfates and limestone and the impact on hydration and mechanical properties of composite slag cements. The total sulfate content was varied at 2, 3 and 4 % by adding ground anhydrite while the aluminate and carbonate contents were kept constant. Samples were analyzed for kinetics of reaction, hydrates formed and mechanical properties at 0.5w/b. The amount of added sulfate influences hydration and compressive strength. The highest compressive strength was observed at 3% sulfate content.
