Types & Summary of Cracks in Reinforced Concrete Beams

Shrinkage Cracks in Reinforced Concrete Beams: Shrinkage cracks in reinforced beams occur during two stages, which are a pre-hardening stage and hardened stage. In pre-hardening stage, these types of cracks are called as plastic shrinkage cracks & in the hardened stage they are known as drying shrinkage cracks.
