Shrinkage in concrete refers to the reduction in volume that occurs as the concrete dries and loses moisture over time. Creep, on the other hand, is the tendency of concrete to deform permanently under sustained load. Both are intrinsic properties of concrete that are influenced by the mix’s composition, environmental conditions, and the concrete’s age at loading. Shrinkage primarily results from the loss of water through evaporation and the resultant capillary forces pulling particles closer. Creep occurs due to the movement of water within the gel pores of cement paste and the subsequent viscoelastic behavior of the cement matrix under load.
