Based on the results of this investigation in which the longest steam curing time was 72 hours, it was concluded that increasing the curing times did not adversely affect the strength of the concrete. However, at the later stages of steam curing, gains in strength were smaller than at the earlier stages. Specimens steam cured for durations beyond 24 hours and then air cured for a combined curing of 28 days attained strength values in the range achieved by moist curing at 28 days.
