Hydration Characteristics and Cementious Properties of Pyrolytic Steel Slag
This study was to investigate the hydration characteristics and cementious properties of pyrolytic steel slag（PSS）. Initially, PSS pastes were made to determine the hydration characteristics of PSS and the results indicated that the hydration activity of PSS with 6.4% gypsum content was stronger than that of paste with pure PSS. Afterwards, compressive strength of mortars were tested and the results showed that cement mortars with 0% to 30% replacement of PSS satisfied the requirements of activity index class of 80% at 28 days. As an activator, gypsum was supiror to calcium hydroxide in performance.
