Disadvantages of reinforced concrete are
- The tensile strength of reinforced concrete is about one-tenth of its compressive strength.
- The main steps of using reinforced concrete are mixing, casting, and curing. All of this affects the final strength.
- The cost of the forms used for casting RC is relatively higher.
- 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.
- Shrinkage causes crack development and strength loss.
- 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.
- 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.
- Due to reinforcement, probability of cracking in concrete increases, because of shrinkage and creep in freshly lay concrete and hardened concrete.
- 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.
