Why Concrete Needs Reinforcement
Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of ...
Concrete is great at putting up with stress in the form of compression. It can take a lot of squeezing abuse before it gives up. It's terrible at handling tensile stress though, ...
When these stresses exceed the tensile capacity of the concrete, surface cracking occurs. Cracks start on the surface and grow downward creating V-shaped cracks.
PNNMumbai (Maharashtra) [India], July 11: In this quest to become one of the topmost economies in the global platform, proper infrastructure and a high living standard always play a key role.
