| Abstract: | The experiment of creep fracture for concrete by using a serious of three points bending specimens. The relationships between stress intensity factor levels and time of creep fracture have been obtained. The effect of concrete curing period on time of creep fracture has been discussed. Furthermore, the crack propagation has been analized. |
