Saturated or sealed specimen strength is used to evaluate the structure strength. But it is being revealed that the strength gain of structure which has history of higher temperature at early stage of hydration is lower and that saturated or sealed specimen strength is unable to evaluate it because of their big difference. As cement content of high strength concrete is very large and high strength concrete is applied to relatively larger member of structure, the temperature inside its structure is easy to be raised and strength gain is greatly affected. In that case heat insulated specimen strength is suitable to elvaluate the structure strength.
