As the scale of structure becomes larger, the temperature crack of massive concrete structure is caused by the phenomenon which the mass concrete volume is restricted in the inside or outside part due to the temperature variations induced by the hydration heat of cement. So, we should prepare the method to reduce reasonably the hydration heat for the control of temperature crack. Therefore, this study presents the hydration heat analysis to verify the control effect of temperature crack when we consider the different placement layers and block placement according to the different concrete mixtures.To this end, we consider the low heat mixture concrete and block placement effect. This is, we place the low heat mixture concrete in the lower layer by using the admixture to reduce the hydration heat, and then place the general concrete or early strength type concrete in the upper layer. Also, we evaluate the control results of the temperature crack by comparing the distributions of temperature and stress in the middle and surface parts |
