Correct option is A
Creep in concrete refers to the
progressive increase in strain under sustained stress over time. Even under a constant load, the deformation (creep strain) in concrete increases due to the gradual rearrangement of the internal structure of the concrete. The primary characteristic of creep is its
time-dependent nature, meaning that it continues to occur as time progresses.
While
temperature and
moisture conditions may influence the rate of creep, the phenomenon itself is inherently
time-dependent.
