| Abstract |
The several methods to evaluate the harmful temperature crack according to the hydration heat of mass concrete are required as the buildings become massive. This study considers the various variables to influence the occurrence of hydration heat in the hydration heat analysis. First, some different heat transfer coefficients according to curing conditions are applied in the analysis process to evaluate the hydration heat difference of the internal and external parts of mass concrete. Also, the occurrence effect of hydration heat by the use of coarse particle cement is verified through the comparison with ordinary portland cement. Specifically, the thermal stress and temperature crack coefficients are analyzed for the effective evaluation of hydration heat analysis results. |
