What are the implications of steam curing to High Slag Cement Concrete?

Hydrothermal curing is particularly good for High Slag Cement Concrete. Steam curing with slightly higher temperature as compared to OPC cement can be adopted in order to increase the strength of the High Slag Cement Concrete precast structures. However, high Slag Cement Concrete has slower early-age strength development than OPC concrete and it is sensitive to the influence of temperature, the user has to appropriately adjust or delay the time for concrete pre-curing (especially for the production during winter season). This is to ensure that the concrete structures possess sufficient preliminary strength before putting into the autoclave, such that the best steam curing effect is attainable.
