31/3/2020 · Steam curing of concrete is the method of curing the concrete elements in water vapor. This curing is performed either under atmospheric pressure or high-pressure steam. The steam curing method is preferred where there is a need for accelerated strength gain and the concrete requires additional heat to perform hydration.

[Steam Curing] Steam Boiler is Optional For Concrete …

As mentioned previously, unlike steam curing of conventional concrete with a typical water-to-cement ratio of 0.35–0.6, concrete samples subjected to accelerated carbonation normally feature a very low water-to-cement ratio that ranges from 0.05 to 0.28. 12 Further increase of the water-to-cement ratio generally leads to a decrease of the CO 2 curing degree and compressive strength of
