The effect of hot air curing on strength development of RPC at different temperatures and durations are studied in detail.
Different methods for the initial moist air curing significantly impacted the precision of testing method and resulted in the strength variation of cement on 1 d.
All concrete specimens were either water cured or atmosphere (Air curing) cured with relative humidity of 60% and 20 °C for 28 days.

The results showed that the highest and lowest compressive strengths are attributed to the specimens of OPC mortar water cured using grounded OPC for duration of 6 h (OM G6 wc) and OPC mortar air cured under room temperature with oven heated after demoulding of the specimens at 60 °C for duration of 20 h (OM OH ac), respectively.
One set was cured under normal curing conditions (i.e. in a conventional curing room until the day of testing or in the curing room for the first 7 days and air cured for the remaining of the study) and the second set was cured in the curing room for the first 7 days and then exposed to a temperature of 46 °C (115 °F) in the oven on a 12-h based cycles until testing.
