The temperature rise of the concrete in early age affects on long term strength development of concrete in the structure between the age of 28 and 91 days. In this study, comparison between the compressive strength of control specimen subjected to standard curing at 28 days and the compressive strength of core specimens taken from structural members was made, and observations methods of evaluating the concrete strength in structure were discussed. When the maximum temperature of the concrete in the structure exceeds 60℃, the concrete strength in structure may be lower than the compressive strength of the 28 days standard curing specimens.
