| Abstract: | The main factors,including lim it ing extended value,elastic module and thermal deformation,which influenc on cr ack re sistance of mass concrete have been analyzed in this paper.We presented the criterion of crack resistance of the mass concrete and use d it to check the crack resistance of the mass concrete with experiments.After analyzing the rea sons responding for the sit-uations,we got an agreement result.The criterio n can provide us a lot of valid data of protecting the mass concrete in earlier various periods. |
