At the end of steam-curing, the concrete strength is greatly enhanced, reaching more than 50% of the design strength [19,20]. The improvement in the early strength of concrete by steam-curing is because high temperatures accelerate the generation of hydration products [21,22] and reduce the later strength of concrete …
