Disadvantages of Reinforced Concrete

Disadvantages of reinforced concrete are

1. The tensile strength of reinforced concrete is about one-tenth of its compressive strength.
2. The main steps of using reinforced concrete are mixing, casting, and curing. All of this affects the final strength.
3. The cost of the forms used for casting RC is relatively higher.
4. For multi-storied building the RCC column section for is larger than steel section as the compressive strength is lower in the case of RCC.
5. Shrinkage causes crack development and strength loss.
6. First and the main factor that increase the cost of your normal project is the “time of construction”. Construction time increases in case of reinforcement.
7. Reinforced concrete can corrode easily because of the presence of steel. Steel is heterogeneous material while concrete is a homogeneous material. Therefore, if both materials will be used in combination than quality control will be very difficult.
8. Due to reinforcement, probability of cracking in concrete increases, because of shrinkage and creep in freshly lay concrete and hardened concrete.
9.  If spacing in aggregates will not be proper, then weak links increases in between steel and concrete and now if either steel or concrete fails then whole structure will be failed.
