WebMay 14, 2024 · Since concrete is a significantly brittle material and exhibits a very poor tensile strength, it cracks easily and results in freeze and thaw damage, scaling, discoloration, and also steel corrosion. Therefore, to sort out these issues, fibers are added to concrete to control the cracks and crack growth [ 1 ]. WebCreep and shrinkage of concrete are two physical properties of concrete.The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.
