Types & Causes of Concrete Cracking - EngineeringCivil.org
- These cracks may occur in reinforced concreteelements after the hardening state. Flexural cracks are vertical cracks that develop at the tension zone of the member up to their neutral axis. Width of these cracks are usually wider at the mid-span of the member. This is because the maximum strain in reinforcement occurs at this zone. Flexural cracks ...
