In this study, effects of steam curing on some mechanical properties of concrete; compressive and split tension strength, and modulus of elasticity of hardened concrete were investigated. For these purposes, three different concrete mixes were prepared. Three different curing temperatures as 40 °C, 60 °C, and 75 °C, and also two different curing durations as 4h and 8h were applied in the program. The interpretation of the results of tests revealed that the rate of development in early strength values of steam-cured specimens were relatively higher with respect to their controls as the steam curing temperatures were increased. However, the gain in early strength values became smaller according to the control specimens for higher strength classes of concretes. Moreover, the rate of improvement in early strength values of steam-cured specimens was also greater according to the controls when the steam curing durations were increased. Finally, slight reductions in late strength values of all steam- cured specimens were observed when they were compared with the control specimens.
