Betongs hållfasthet vid moderata temperaturbelastningar
Reactor vessels in nuclear power plants are contained by a large prestressed concrete structure, which is subjected to elevated temperatures during operation. According to the American standard ACI 349, which is also used in Sweden, two limits should be carefully considered. These temperature limits are 66°C (150°F) and 93°C (200°F). Previous studies usually focus on concrete subjected to fire, th
