Brittle Creep Failure, Critical Behavior, and Time-to-Failure Prediction of Concrete under Uniaxial Compression

Figure 9

The log-log plot of the creep slopes of the secondary stage and . It is indicated that there is an almost linear relation; namely, the solid straight line is the fitted result. So, the lifetime for each specimen shows a power-law dependence on the secondary creep rate with an exponent of −1.
