Оригинален текст - Английски - steam cured precast concrete

The quality of a steam cured precast concrete is affected by curing time and temperature variables. Steam curing might cause micro-cracks along the interface of aggregate and cement paste. It has been reported that the strength of concrete by steam curing could decrease in later stages such as 28 days or 90 days, while compared with concrete cured in air or in water.
