Abstract
The experiments and analyses were conducted in order to estimate the effects of heat controlling agent on the thermal stress reduction in massive concrete structures. The relation between the heat generation and the strength to the amount of agent was investigated. Both the effects on heat reduction and accuracy of computation were analyzed. On the state of stress suppression, it was proved that the results of comparison between mock up experiments and thermal stress analyses were in good agreement. The rate of reduction was estimated on the analytical application to wall structures with different thickness. It was also found that the effect of stress reduction was obtained in the application of layered casting method.
