· These results indie that, similar to steel slag powder, steel slag aggregate has reacted to some extent and produced some hydration products at 28 d, which is conducive to the connection of steel slag aggregate with the hardened paste. This may be attributed to the activating effect on the steel slag aggregate produced during the initial hightemperature curing.
