Hydration of blended cement with high volume iron-rich ...

The hydration of blended cements with up to 70 wt% iron-rich slag was investigated. Isothermal calorimetry revealed a retarding effect of the slag on Portland cement hydration during the first day, while from 2 days onwards the reaction extent of C 3 S, C 3 A and C 4 AF increased. The slag reacted to 20–30% after 150 days resulting in AFm phases, as well as a new phase with …
